摘要

Reactivities of tetraphenyldisilane (TPDS), tris (trimethylsilyl) silane, and tributyltin hydride in the radical ring expansion of α-haloalkyl cyclic β-keto esters were examined. Among these reagents, TPDS was found most effective for the preparation of medium-sized cyclic compounds in terms of yields and ring-expansion/reduction selectivity.
