Monochlorination at the 1-position with sulfuryl chloride, followed by methanolysis converted 2-acetylenic phenyl sulfides into 1-methoxy-2- acetylenic phenyl sulfides. Oxidation with chromic acid gave 2-acetylenic carboxylic acids. Oxidation of 2-acetylenic phenyl sulfides with Oxone and hydrogen peroxide in acetic acid gave the corresponding sulfoxides and sulfones respectively. Diethylamine addition to the triple bond produced enamines which were hydrolyzed with aqueous hydrochloric acid to the corresponding 1-sulfinyl and 1-sulfonyl-2-ketones.

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.

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.
