Rhodium-catalyzed arylation of acylsilanes with sodium tetraarylborates
摘要:
Rhodium(I)-catalyzed arylation of benzoylsilanes with sodium tetraarylborates affords alpha-silyl benzhydrols, benzhydryl silyl ethers, benzhydrols, and diaryl ketones selectively depending on the catalyst, solvent, and temperature. (C) 2014 Elsevier B.V. All rights reserved.

Reaction of silylthioketone 7 with lithium diethylphosphite at −98°C afforded a S-attack product 8 and formal C-attack products 10 and 11, which were formed by S-to-C migration of the phosphoryl group in the S-adduct followed by C-to-S migration of the silyl group (Thia–Brook rearrangement), in a ratio depending on the conditions. The relative facility of the Thia–Brook rearrangement was compared
