Abstract
Ethyl triphenylstannylacetate and ethyl α-triphenylstannylpropionate reacted with aldehydes and acetals to give β-hydroxy and β-alkoxy esters at room temperature in the presence of TiCl 4, in moderate yields. Under these conditions ethyl triphenylgermylacetate and ethyl trimethylsilylacetate did not work.
