(E)-α-Aryltellurenylvinylsilanes have been synthesized stereoselectivelyvia the hydromagnesiation of alkynylsilanes, followed by the reaction with aryltellurenyl iodides. (E)-α-Aryltellurenylvinylsilanes can undergo the cross coupling reaction with Grignard reagents in the presence of Ni(PPh3)2Cl2 catalyst to afford (Z)-1,2-disubstituted vinylsilanes in good yields.
