Lactams form solid, isolable complexes with the three dihydroxybenzenes, o,o’-biphenol and 2,3-naphthalenediol, in which lactam-phenol ratios of 1:1, 2:1, 3:1 and even 4:3 were observed.These ratios can be determined with precision by a gas chromatography method which is described.IR spectroscopy indicates that the bonds linking lactam and phenol are O-H…O and/or N-H…O hydrogen bonds.Structures for the complexes are suggested.

Acetylated 4,4?-biphenydiol (ABD) and biphenyl-4,4?-dicarboxylic acid (BDCA) were polycondensed in inert aromatic reaction media at various temperatures and monomer concentrations. At temperatures ?300C oligoesters were obtained, which according to infra-red and 13C nuclear magnetic resonance cross-polarization/magic-angle spinning spectroscopic characterization preferentially possess two carboxyl end-groups. Furthermore, polycondensations were conducted at 400C whereby high-molecular-weight polyesters were obtained. Electron microscopy revealed the formation of lengthy crystallites, but true needle-like whiskers were never formed. Analogous polycondensations were conducted with acetylated hydroquinone and BDCA or with ABD in combination with terephthalic acid. Furthermore, all three polyesters were prepared by polycondensation of the free diphenols with terephthaloyl chloride or biphenyl-4,4?-dicarboxylic acid dichloride in Marlotherm-S at 400C. Highly crystalline polyesters were obtained whenever the polycondensations were conducted at 400C in Marlotherm-S, but in all cases the morphology was that of irregular particles. Wide-angle X-ray diffraction powder patterns measured with synchrotron radiation up to 440C revealed that all three polyesters undergo a gradual transition from an orthorhombic crystal lattice to pseudo-hexagonal and finally to hexagonal chain packing with increasing temperature. These transitions cover a temperature range of more than 400C. Only in the case of the polyester derived from hydroquinone and BDCA was a reversible first-order phase transition observed around 506C.

A novel chiral phosphine-oxazoline ligand 3 with an axis-unfixed biphenyl backbone was prepared. This ligand existed as a mixture of two diastereomers in equilibrium in solution. However, when it was coordinated with palladium(II), only one of the two kinds of possible diastereomer complexes with different axial chirality was formed. When this axis-unfixed chiral ligand was used, up to 90% ee was attained for the palladium-catalyzed asymmetric allylic alkylation. Georg Thieme Verlag Stuttgart.

Synthesis and study of an ortho-phenol polymer, a highly functionalized polyphenylene, have been conducted. A dibromo ortho-biphenol monomer was synthesized and its homocoupling in the presence of Ni(1,5-cyclooctadiene)2 followed by hydrolysis led to the formation of an ortho-phenol polymer. This polymer was soluble in common organic solvents. It was characterized by gel permeation chromatography, UV-vis, IR, 1H and 13C NMR spectroscopic methods. The use of this polymer in the Lewis acid-catalyzed reaction of phenylacetylene with benzaldehyde in the presence of diethylzinc was studied. It was found that the polymer when treated with 1/4 equiv. (relative to the phenol unit of the polymer) of Ti(OiPr)4 generated a much more active Lewis acid catalyst than when treated with excess Ti(OiPr)4. This indicates that different types of catalytic sites in the polymer have been produced under these conditions.

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.Product Details of 1806-29-7, you can also check out more blogs about1806-29-7

Reaction systems of boronic acid (RB(OH2), R = phenyl or 3-fluorophenyl) with diols and no proton ambiguity were elaborately set up, and kinetic measurements were conducted to elucidate the relative reactivities of RB(OH)2 and RB(OH)3-. In the reactions of phenylboronic and 3-fluorophenylboronic acids with propylene glycol, the reactivity order was: RB(OH)2 >> RB(OH)3 -, whereas in the reactions of 3-pyridylboronic acid with Tiron and 2,2?-biphenol, the reactivity of RB(OH)2 was comparable to that of RB(OH)3-. These results are in contrast to those that have been previously reported, and widely accepted for over thirty years, that concluded that the reactivity of RB(OH)3- is several orders of magnitude higher than that of RB(OH)2. The reactivity of Tiron with 3-pyridylboronic acid is affected by the protonation of one of its sulfonate groups.

Heterobimetallic complexes containing titanium and palladium were prepared from O,N,O-N,N multidentate ligands. The ligands each contained an O,N,O-tridentate part based on a 2,6-lutidine scaffold and an N,N-bidentate di(pyridin-2-yl) part. The O,N,O-moiety selectively coordinated to a titanium atom on treatment with titanium(tetraisopropoxide), although one of the di(pyridin-2-yl) groups in the N,N-moiety coordinated to the titanium atom. The N,N-bidentate di(pyridin-2-yl) moiety coordinated to the palladium atom on treatment with bis(benzonitrile)palladium(II) chloride to afford a heterobimetallic complex. The dynamic behavior of the complexes in solution was studied by NMR spectroscopy. Heterobimetallic complexes containing titanium and palladium were prepared from O,N,O-N,N multidentate ligands and structurally characterized.
