A synthetic method for the preparation of α-stannyl α,β-unsaturated esters is described. The lithium enolate derived from tert-butyl α-(tri-n-butylstannyl)-α-(trimethylsilyl)acetate reacts with aldehydes to give moderate to good yields of α-stannylated products. The method is not applicable to enolizable ketones.

Three t-butyl (trialkylstannyl)(trimethylgermyl)acetates were synthesized and subjected to the Peterson-type reaction with carbonyl compounds. t-Butyl 2-(tri-methylgermyl)-2-alkenoates were obtained as the main products from (tri-n-butyl-stannyl) (trimethylgermyl)acetate, along with 2-(tri-n-butyl-stannyl)-2-alkenoates and 2-alkenoates as minor products
