Abstract

The coupling reaction of bromo- and - iodopyridines 1 with phenylboronic acid (2a) by Pd(Ph3 P)4 provides a convenient route to phenylpyridines, even when electrondonating or - withdrawing substituents are present. The method is also successful for the preparation of other phenylated N-containing heterocycles 5 as phenylquinolines and -pyrimidines.
