The orthopalladation of N-ylides [H x C y N–CHC (O) Ar](H x C y N= pyridine, benzylamine, imidazole, aniline, and phenylpyridine; Ar= aryl) has been studied. The incorporation of the Pd atom to these substrates is regioselective, since the orthopalladation is produced, in most of the cases, only at the aryl ring of the benzoyl group with concomitant C-bonding of the N- ylide. The X-ray structure of one representative example is reported. Factors governing the ...
