Intermolecular Rhodium(II)-Catalyzed Reactions with Silicon-Substituted Carbonyl Ylides

Abstract

[reaction: see text] The Rh(II)-catalyzed reaction of benzyl 2-trialkylsilyl-2-diazoacetates with various acyclic and cyclic ketones affords novel dioxolanones via silicon-substituted carbonyl ylides in up to 98% yield.
