Palladium-catalyzed cross-coupling reactions of dimethyl- and diethylzinc with unsaturated organotellurium compounds †
摘要：
The cross-coupling reaction of diethyl- or dimethylzinc compounds with disubstituted vinylic tellurides as electrophilic partners is described. These cross-coupling reactions were catalyzed by Pd(PPh 3) 4/CuI and were shown to be general, allowing the formation of a new sp 3– sp 2 carbon–carbon bond. Good yields and high stereoselectivity were observed in all cases.
