experimental part, p. 10901 - 10907 (2010/02/27)
Thioacetals were found to be effective precursors to generate and accumulate alkoxycarbenium ions based on direct and indirect cation pool methods. Alkoxycarbenium ions thus generated reacted with carbon nucleophiles such as allylsilanes and enol silyl et
Lithium bromide, a novel and highly effective catalyst for monothioacetalization of acetals under mild reaction conditions

Lithium bromide is efficient as a catalyst for the monothioacetalization of acetals under mild reaction conditions to provide products in excellent yields with high chemoselectivity.

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.

, p. 1661 - 1664 (2007/10/02)
Monothioacetals are obtained by treating the corresponding acetals with organotin thiophenoxides in the presence of BF3*OEt2.The reaction proceeds under mild conditions to provide the desired compounds with high selectivity.
