The solid acid, tin hydroxide-embedded montmorillonite, catalyzes the unprecedented alkylation of various silicon enolates with primary, secondary and tertiary benzylic alcohols as well as secondary allylic alcohols. The acid catalysis of Sn-Mont was not only higher than that of the other ion-exchanged montmorillonites (M-Mont; M?=?H, Ti, Fe and Al), but also higher than that of the typical homogeneous acid catalysts such as BF3·OEt2, TMSOTf and TfOH.

Rhodium(I)-catalyzed arylation of benzoylsilanes with sodium tetraarylborates affords α-silyl benzhydrols, benzhydryl silyl ethers, benzhydrols, and diaryl ketones selectively depending on the catalyst, solvent, and temperature.
Reaction of silyl thioketones with lithium diethylphosphite: First observation of Thia-Brook rearrangement

, p. 449 - 454 (2007/10/03)
Reaction of silyl thioketone 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 with that of the Brook rearrangement using the (t-butyldimethylsilyl)diphenylmethyl derivatives 22 and 23.
