Abstract
Cesium and potassium fluorides promoted trialkylsilylation and tributylstan nylation of terminal alkynes with trifluoromethyltrialkylsilanes and -tribu tylstannane were found to give 1-silyl- and 1-tributylatannyl-alkynes in hi gh yield. The present reactions are applicable to 1-alkynes having a wide r ange of functional groups such as acetal, iodo, silyl, amino, amido and car bonyl (except for aldehyde) groups.
