To obtain further insight into the new ruthenium-catalyzed reaction of carbon–hydrogenbonds in aromatic ketones with olefins, the effect of various substituents at the aromatic ring is examined. Reaction of o-methylacetophenone with triethoxyvinylsilane (2) in the presence of [Ru(H)2(CO)(PPh3)3] (3)as the catalyst gave the 1 : 1 addition product in quantitative yield. Similarly, the ketone having
Nitro-Power! An exceptionally general electrophilicamination of zinc organyl compounds was developed, and yields alkylated aromatic aminoboranes from commercially available nitroarenes. The partially reduced nitro group is directly engaged as an electrophilic nitrogen intermediate. The aminoboranes were reacted with electrophiles, thereby incorporating two different substituents at the N atom of the
