摘要：

The reaction of ω-(o-iodoaryl)- and ω-(Z-β-iodoalkenyl)alkynes with organometals containing Zr, Sn, Al, or B in the presence of a catalytic amount of a palladium-phosphine complex, such as Pd(PPh3)4, proceeds predominantly via initial cyclic carbopalladation followed by cross coupling, whereas the corresponding reaction of organozincs tends to be dominated by direct cross coupling. © 1990.
