Visible-light-promoted sulfidation and phosphorylation of arylhydrazines for the synthesis of aromatic sulfides and diarylphosphoryl hydrazides were developed using the organic dyes rose bengal and Na2-eosin Y as photocatalysts, respectively. This strategy offers an efficient and mild transition-metal-free synthetic protocol for the formation of C-S and N-P bonds from arylhydrazines.

A mild and efficient method for the synthesis of unsymmetrical diaryl- and triarylmethanes through a B(C6F5)3 catalyzed reduction of para-quinone methides and fuchsones respectively, using the Hantzsch ester as a reducing source has been developed. Detailed mechanistic investigations revealed that the reaction actually proceeds through a Lewis acid-base pair complex derived from B(C6F5)3 and the Hantzsch ester.

experimental part, p. 2290 - 2297 (2011/04/14)
The composition of the products of the reaction of 2,6-disubstituted phenols with allyl alcohol and its derivatives in an alkaline medium was investigated, the conditions for carrying out the reaction with the predominant formation of 4-(3-hydroxypropyl)-2,6-dialkyl(aryl)phenols were found, and its mechanism was suggested. The reaction was examined on an industrial scale. An important result is the practical demonstration of alkaline catalysis performed under homogeneous conditions with participation of phenols, when the used alkaline catalyst is recovered in the process without the formation of waste waters.
