Various ketones are readily reduced by an acid-stable NADHmodelcompound, 10-methylacridan (AcrH2), in the presence of perchloric acid in acetonitrile. Rates of the acid-catalyzed reduction of ketones by unprotonated AcrH2 are well correlated with rates of the acid-catalyzed photoinduced electron-transfer reactions from the excited state of [Ru(bpy)3]2+ to the ketones.

availability of the nitroarene, the sole mediator of the reaction. Because of the anaerobic conditions of the transformation, a noteworthy expansion in substrate scope can be obtained compared to prior reports. Mechanistic studies support that the photoexcited nitroarenes engage in successive hydrogen atom transfer and radical recombination events with hydrocarbons, leading to N-arylhydroxylamine ether intermediates

Metalation of a series of 1- and 2-alkynes with subsequent treatment with diborane and oxidation gave 1,3-diols exclusively. Deuteroboration of the lithiated acetylenes established the occurrence of a displacement of one of the B atoms by deuterium in gem-diboronated compounds. Hydroboration of several acetylenes and acetylides was also studied.
