Studies of triphenylsilanethiol addition to alkynes: Preparation of vinyl sulfides
Beauchemin, Andre,Gareau, Yves
, p. 187 - 192 (2007/10/03)
The scope and limitations of triphenylsilanethiol (1) a solid hydrogen sulfide equivalent, were investigated in free radical reactions to terminal alkynes. The triphenylsilylthioenol ether intermediate thus obtained was deprotected with Cs2CO3 in the presence of various electrophiles to yield mixtures of E and Z vinyl sulfides. The ratio of E and Z isomers could be controlled by varying the concentration of the starting alkynes.
Photochemical Conversion of 3-Azido-2-vinylthiophenes into Thienopyrroles and of 2-Azidostyrenes into Indoles. High Migratory Aptitude of Sulphur Substituents

On photolysis in acetonitrile 3-azido-2-vinylthiophenes (8a-h) give thienopyrroles (10), (16), (18)-(20), (23), (24), (26) and 2-azidostyrenes (9a-d) give indoles (11) and (22).A mechanism is proposed involving formation and 1,5-electrocyclisation
