Abstract
[GRAPHICS] Two new and very efficient procedures (Procedures A and B) are reported for the Pd-catalyzed cross coupling of aryl electrophiles; with terminal alkyn es via their in situ conversion into alkynylzinc derivatives. Procedure A i s particularly valuable in cases where electron-deficient alkynes are used, while Procedure B is operationally simple and very satisfactory in less de manding cases.
