Selectiveruthenium-catalyzed reductive coupling of primary amides under hydrosilylation conditions is achieved using an one pot procedure. Using 3 equiv. of phenylsilane and [RuCl2(mesitylene)]2 (1-2 mol%) as the catalyst at 100 degrees C under neat conditions, secondary symmetric amines were obtained in good yields and with high chemoselectivities.

A rewritable optical information recording medium including a recording layer composed of an organic dye film is provided, in which recording and erasing information can be performed reversibly by laser light irradiation. A rewritable optical information recording medium including at least one organic dye film which is substantially made of only at least one kind of organic dye compounds as a recording film is provided. The recording and erasure of information are performed by a reversible physical change of the organic dye film substance caused by laser light irradiation. Specifically, data recording is performed by a physical change locally caused by the irradiation of recording laser light, data reproduction is performed by detecting change in intensity of returned light of reproducing laser light having less power than the recording laser light, and data erasure is performed by applying at least once continuous light or pulse light having laser power more than the reproducing laser light and less than the recording laser light. The physical change is a change in shape.
