Reaction of the complexes cis- with acetoacetanilide, o- or p-acetoacetanisidide mediated by silver(I) oxide gave, under mild conditions, high yields of the metallalactam complexes (R = Ph, C6H4OMe-o or p).The complexes have been fully characterised by multinuclear NMR spectroscopy, fast atom bombardment mass spectrometry, and by a single-crystal X-ray diffraction study carried out on the 2,2'-bipyridyl palladium derivative .The complex contains a slightly puckered palladalactam ring system (fold angle 17.5 deg).Reaction of acetoacetanilide with the zerovalent platinum complex in air gives exclusively the peroxometallacyclic complex , while reaction with gave a mixture of the peroxometallacycle plus the platinalactam complex .
