Abstract
In the presence of AIBN, tributylstannyl enolates derived from aromatic ketones reacted with electron-deficient alkenes and a variety of alkynes to give the corresponding carbostannylated adducts. The reactions with methyl acrylate gave α-tributylstannylmethyl-γ- ketoesters, unlike the known Michael-type reaction of stannyl enolates forming δ-ketoesters. The carbostannylation of alkynes proceeded in an anti addition mode to afford β, γ- ...
