Ground and excited singlet (S1) state interactions of 2,2?- and 4,4?-biphenyldiols with proton acceptors

Proton-transfer interactions of 2,2?- and 4,4?-biphenyldiols with urea (U), N-methylurea (MU), and triethylamine (TEA) have been investigated in methanol solutions using optical absorption as well as steady-state and time-resolved fluorescence measurements. In the ground state, both 2,2?- and 4,4?-biphenyldiols do not interact with weak proton acceptors, like U and MU. In the excited singlet (S1) state, only the 2,2?-biphenyldiol is seen to transfer a proton to U and MU, via the formation of intermolecular hydrogen-bonded exciplexes as intermediates. With TEA, a strong proton acceptor, both 2,2?- and 4,4?-biphenyldiols undergo an efficient proton-transfer reaction in their S1 state. In the ground-state, however, only 2,2?-analogue is seen to transfer a proton to TEA. The differences in the proton-transfer behavior of 2,2?- and 4,4?-biphenyldiols with different proton acceptors have been rationalized in terms of the presence and absence of intramolecular hydrogen bonding in the two diols.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1806-29-7, help many people in the next few years., Synthetic Route of 1806-29-7

Perylene bisimides with rigid 2,2?-Biphenol bridges at bay area as conjugated chiral platforms

(Figure Presented) Facile nucleophilic substitution of two chlorine atoms by 2,2?-biphenol at one of the two bay areas (1,12- and 6,7-positions) of core-tetrachlorinated perylene bisimide afforded a novel, completely desymmetrized perylene bisimide building block, which could be further functionalized by substitution of the remaining two chlorine atoms. The atropisomers (P- and M-enantiomers) of the core twisted perylene bisimides were resolved by HPLC on a chiral column at room temperature, and the activation parameters for racemization were elucidated.

Substitution reactions of dichlorobis(betadiketonato-O,O?) titanium(IV) complexes with aryl diolato ligands: An experimental and computational study

Substitution reactions of complexes Ti(beta-diketonato) 2Cl2, in which the two monodentate Cl- ligands are replaced by different bidentate aryl-diolato ligands (catechol, naphthol, biphenol, binaphthol, or methylenebinaphthol), produce remarkably hydrolytically stable titanium(IV) complexes with 5-, 7- or 8-membered chelating rings. The lability of the chlorine ligand in the parent compound is dependent on the strength of the electron donating properties of the spectator beta-diketonato ligand around the titanium centre. The reactivity of Ti(RCOCHCOR?) 2Cl2 complexes according to the beta-diketonato ligand (RCOCHCOR?)- follows the order (PhCOCHCOPh)- > (PhCOCHCOCH3)- > (CH3COCHCOCH 3)-, in line with results for other known transition metal complexes. Detailed substitution kinetics along with the X-ray crystal structure of a mono-chloride Ti(beta-diketonato)2(Cl)(naphthol) reaction intermediate are reported. DFT calculations on the reaction of Ti(acac)2Cl2 with different aryl-diolato ligands reveal that chlorine substitution proceeds via a two-step interchange mechanism with the formation of two seven-coordinated transition states and one six-coordinated intermediate. The computed mechanism agrees very well with experimental kinetic and X-ray data. . 2013 Elsevier Ltd. All rights reserved.

Stereoselective synthesis of spirooxindoles by palladium-catalyzed decarboxylative cyclization of gamma-methylidene-beta-valerolactones with isatins

Image Presented A new synthetic method of spirooxindole derivatives has been developed by way of a palladium-catalyzed decarboxylative cyclization of gamma-methylidene-beta-valerolactones with isatins. By employing a newly prepared phosphoramidite ligand, the reaction proceeds smoothly with excellent diastereoselectivity. Preliminary results of its application to asymmetric catalysis using a chiral phosphoramidite ligand are also described.

2,2?-biphenols via protecting group-free thermal or microwave-accelerated suzuki-miyaura coupling in water

User-friendly protocols for the protecting group-free synthesis of 2,2?-biphenols via Suzuki-Miyaura coupling of o-halophenols and o-boronophenol are presented. The reactions proceed in water in the presence of simple additives such as K2CO3, KOH, KF, or TBAF and with commercially available Pd/C as precatalyst. Expensive or laboriously synthesized ligands or other additives are not required. In the case of bromophenols, efficient rate acceleration and short reaction times were accomplished by microwave irradiation.

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
