Nucleophilic addition to thioalkynes was investigated under various catalytic conditions with gold(I) complexes being identified as the optimal catalysts. Structural evaluation of the product revealed an unexpected cis-addition, arising from a gold-associated thioketene intermediate. Based on this interesting mechanistic insight, a gold(I)-catalyzed thioether addition to thioalkynes was developed as a novel approach to prepare ketene dithioacetals with good yields and high efficiency.

A new method for the preparation of α-fluorovinyl thioethers is reported which involves the hydrofluorination of alkynyl sulfides with 3HF·Et3N, a process that requires Lewis acid activation using BF3·Et2O and TiF4/s

Regio- and stereoselective addition of a silyl-substituted alkynyl sulfide to various terminal alkynes proceeds in the presence of a palladium catalyst to give (Z)-1-thio-1,3-enynes, which are useful building blocks for the synthesis of polysubstituted 1,
Synthesis of alkynyl sulfides resulting from a novel ring cleavage of 5-chloro-1,2,3-thiadiazoles in the presence of organometallic reagents

5-Chloro-1,2,3-thiadiazoles 2a,b were treated with organolithium and Grignard reagents giving a novel ring cleavage with the loss of nitrogen and chloride anion, resulting in the formation of alkynyl sulfides 9-14. The results indicate that the mechanism of the reaction involves a concerted trans-elimination of the leaving group.
Neighboring the effect in the oxidation of α-Stannyl phenyl vinyl sulfides
Glass, Richard S.,Guo, Qin,Liu, Yunqi
, p. 12273 - 12286 (2007/10/03)
α-Stannyl vinyl sulfides were generally prepared by hydrostannylation of thioacetylenes catalyzed by Pd(PPh3)4. The regio- and stereochemistry of the products was determined unequivocally in three cases by X-ray crystallographic stru
