Soil organic matter (SOM) is a major component of the biogeochemical cycle contributing to soil general properties and conservation. The progressive depletion of the SOM in Mediterranean ecosystems results in an increased advance of desertification. The SOM not only plays a crucial role in soil resilience, but also represents a repository of environmental information on soil forming factors in particular climatic constraints. In this research, analytical pyrolysis (Py-GC/MS) is used to study SOM composition in 30 soils under contrasting bioclimatic scenarios as defined by the classical Emberger (Q) index. Partial least squares (PLS) regression using the major pyrolysis compounds as descriptors allowed to predict (P < 0.05) Q indexes, and provide molecular proxies of climatic variability effects on SOM composition. In addition, pyrolytic compound assemblages from soils developed under extreme climatic conditions were compared using a graphical approach based on surface density plots built from the major 193 pyrolysis compounds represented in the plane defined by their H/C and O/C atomic ratios. The differences between the proportions of the individual pyrolysis compounds in terms of the bioclimatic scenarios were also illustrated by a simulation of SOM molecular composition under extreme conditions of aridity or wetness. Although no cause-to-effect is inferred, the results show that SOM composition retains environmental information on the Q index. This is mainly related with the total abundances of methoxyphenols and alkylbenzene compounds, suggesting that the degree of transformation of SOM could be related with the variable accumulation of microbial and plant biomass controlled by climatic factors which is a potential field for future research. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C12H10O2, you can also check out more blogs about1806-29-7

The acid-catalyzed reaction of N-acyl- and N-sulfonyl-O-arylhydroxylamines with benzene proceeded quite smoothly to give 2- and 4-hydroxybiphenyls.The results of product analysis, the orientation of the reaction, and the effects of substituents on the nitrogen atom and on the phenyl ring suggested a mechanism that involves a phenoxenium ion.The phenoxenium ion was trapped by benzene and other various nucleophiles.

A novel dioxa[6]helicene-based supramolecular chirogenic system (1) as a specific chiral recognition host for enantiopure trans-1,2-cyclohexanediamine (2) is reported. Host 1 with an inherent free phenolic group and a (1S)-camphanate chiral handle on the opposite terminal rings of the helicene chromophore acted as an efficient turn on fluorescent sensor for S,S-2 with an excellent enantioselective factor, alpha = KSS/KRR = 6.3 in benzene. This specific host-guest interaction phenomenon is found to be solvent-dependent, which leads to an enantioselective chiral (camphanate) group transfer to the diamine guest molecule. In the case of R,R-2, the de value is up to 68% even at room temperature. Intriguingly, the induced helicity in dioxa[6]helicene diol 6, upon supramolecular hydrogen-bonding interactions, is of opposite sense with positive helicity for S,S-2 and negative helicity for R,R-2, as shown by circular dichroism spectroscopy and in combination with theoretical calculations. This chiral supramolecular system is found to be an excellent host-guest pair for enantiomeric recognition of 2, based on their electronic and steric factors.

As an important branch of heterocyclic compounds, coumarin and its derivatives with diverse potential biological activities have attracted wide attention and have been applied in medical-related fields. In this article, three cyclotriphosphazene derivatives bearing 4-methyl-7-hydroxycoumarin moieties with the numbers of 2, 4, and 6 were synthesized and characterized and their antitumor activities were investigated. All the new compounds were found to display antitumor activity in vitro against breast cancer cell lines (MCF-7 and 4T1 cells) with the IC50 values in the range of 108.72-188.44 muM and 75.93-154.91 muM, respectively. In contrast, the coumarin monomer displayed the values of 4140 muM and 1640 muM (IC50). Our results suggested that the antitumor activity was significantly enhanced when coumarin was introduced onto the surface of cyclotriphosphazenes, thereby providing potent candidate molecules for pharmaceutical applications.

The resin 2,2?-dihydroxybiphenyl-urea-formaldehyde [BPhUF], has been synthesized by the condensation of 2,2?-dihydroxybiphenyl [BPh] and urea [U] with formaldehyde [F] in 2:1:3 molar ratio in presence of 2M HCl as a catalyst. UV-Vis, IR and NMR spectral studies have been carried out to elucidate the structure of resin. Ion exchange properties of this resin have been studied by batch equilibrium method for Fe3+, Cu2+, Ni 2+, Co2+, Zn2+, Cd2+ and Pb 2+ ions over the pH range, 1.5 to 6.5 and in media of various ionic strengths. In presence of chloride and nitrate ions, the uptake of Fe 3+, Cu2+ and Ni2+ ions increases with increasing concentration of electrolyte while for Co2+, Zn 2+, Cd2+ and Pb2+ ions, it decreases with increasing concentration of chloride, nitrate and sulphate ions. The resin shows a higher selectivity for Fe3+ ion over any other ion. Study of distribution ratio as a function of pH indicates that the amount of metal ion taken up by resin increases with the increasing pH of the medium.

The cage monophosphinites CgPOR {where CgP = 6-phospha-2,4,8-trioxa- adamantane and R = C6H5 (La); 2-C 6H4CH3 (Lb); 2,4,6-C 6H2(CH3)3 (Lc); 2,4-C6H3tBu2 (Ld); CH3 (Le); CH2CF3 (Lf)} and diphosphinites CgPZPCg {where ZH2 = 2,2?-biphenol (L g) or 1,2-benzenedimethanol (Lh)} have been made from CgPBr and the corresponding alcohol or phenol. The cage phosphinites are remarkably stable to water. All the ligands La-h have been tested for nickel(0)-catalyzed hydrocyanation of 3-pentenenitrile in the presence of Lewis acids (ZnCl2, Ph2BOBPh2, or iBu2AlOAliBu2), and tentative structure-activity relationships are suggested. The hydrocyanation activities obtained with catalysts derived from monophosphinite Lf (with iBu2AlOAliBu2) and diphosphinite Lh (with ZnCl2) are comparable with the commercial catalyst based on P(OTol)3. The complexes trans-[PtCl 2(L)2] where L = La (1a), Le (1e), and Lf (1f) and the chelate cis-[PtCl2(Lh)] (1h) are reported. From the nuCO values for the complexes trans-[RhCl(CO)(La-f)2] (2a-f), it is concluded that ligand Lf is the most phosphite-like of the monophosphinites. Treatment of [Ni(cod)2] (cod = 1,5-cyclo-octadiene) with L h leads to a mixture of products, one of which was characterized as the binuclear [Ni2(Lh)2(mu-cod)] (3h). The crystal structures of Lh, 1a, 1e, 1f, 1h?2CH2Cl 2, and 3h?3C6H5CH3 are reported.

A readily available cyclic carbamate 1 functions as a general precursor to a range of functionalized piperidine products via a new Pd-catalyzed annulation strategy. An asymmetric catalytic variant provides a rapid and efficient means to access these heterocycles with high to excellent levels of enantiocontrol. Finally, these richly functionalized compounds are amenable to further chemoselective elaboration.
