摘要

The Sn-S bonds in thiostannanes, BunSn (SPh) 4− n, are activated towards acetals in the presence of BF3· OEt2. Acetals of various aldehydes and ketones are converted into the corresponding monothioacetals under mild conditions. Employment of α-enal acetals induces Michael addition to give synthetically useful γ-alkoxyally sulfides.
