Abstract:
Reported herein is the isolation and characterization, for the first time, of a σ-gold allenyl complex as an intermediate in gold catalysis. This intermediate was captured during the study of a novel gold(I)-catalyzed propargylation of carbonyl compounds with propargylsilanes. Notably, the gold-catalyzed propargylation reaction, which proceeds with aldehydes and ketones, can be driven to the formation of either homopropargyl silyl ethers or the in situ synthesis of corresponding 2-silyl-4,5-dihydrofurans.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
