    • Procedure: A solution of the aldehyde or ketone in benzene (0.10 M) with AIBN (0.01 eq.) and tributyltin hydride (1.50 eq.) was carefully degassed with argon and heated to 80° C (bath temperature). After 5–8 hours, thin layer chromatography indicated that the reaction was done. The solvents were removed and the crude oil was subjected to flash chromatography to isolate the desired products.
