Ethylene metathesis of sulfur-containing alkynes
Smulik, Jason A.,Giessert, Anthony J.,Diver, Steven T.
, p. 209 - 211 (2002)
Enyne metathesis of sulfur-containing alkynes and ethylene has been achieved. High yields were obtained by use of thiol esters in the alkyne partner for the cross metathesis with ethylene. The necessary reactivity and functional group compatibility were a
