Conventional thermal and microwave conditions were compared for hydrogen-deuterium (H/D) exchange reactions of aminobenzoic acids catalysed by NaBD4-activated Pd/C or RhCl3 with D2O as the deuterium source. We also investi

A weak absorption of laser light by a nonlinear optical crystal causes a noticeable temperature rise in the crystal.Such absorption may undesirably shift the reflactive indices (some optical characteristics) of the crystal. 3,5-dimethyl-1-(4-nitrophenyl)pyrazole , an excellent nonlinear optical material, was deuterated in order to suppress its absorption in the 1 μm wavelength region.Three deuterated derivatives were synthesized; their crystal structures were identical with that of DMNP.The deuteration of the pyrazole part including the two methyl moieties proved to be more effective than deuteration of the phenyl part (benzene ring) with regard to a reduction of the IR absorption.A good correlation was confirmed between the temperature elevation under laser irradiation and IR absorption.
RUTHENIUM-CATALYSED REARRANGEMENTS OF AZOBENZENES IV. REARRANGEMENTS OF DEUTERATED AZOBENZENES TO 1-PHENYLBENZIMIDAZOLE AND N-PHENYL-1,2-PHENYLENEDIAMINE DERIVATIVES

The ruthenium-catalysed reactions of azobenzene-d10 and 4,4'-disubstituted azobenzene-d8 compounds with non-deuterated tri-n-butylamine, n-butanol or 2-propanol give 1-phenylbenzimidazole or N-phenyl-1,2-phenylenediamine derivatives.The distibution of 1H in the aromatic rings of these products and in the recovered azobenzenes indicated that in all cases ortho-metallation of the azobenzene derivative has occured.The significance of those and other observations for the mechanism of these reactions is discussed.
