Stereoselective synthesis of (Z)-1-silyl-2-stannylethene by palladium-catalyzed silastannation of ethyne and its synthetic transformations

(Z)-1-Silyl-2-stannylethenes were stereo selectively synthesized by silastannation of ethyne, catalyzed by a palladium/tert-alkyl isocyanide catalyst, and the synthetic utilities were demonstrated by their transformations.
