Abstract The preparation of M(diene · OCH3)(L L)Y complexes (M = PdII, diene = 1,5-cyclooctadiene, endo-dicyclopentadiene, L L = 2,2′-bipyridyl, 1,10-phenanthroline, Y = hexafluorophoshate, diene = dicyclopentadiene, L L = 1,2-bis-(diphenylphosphino)ethane, Y = hexafluorophosphate; diene = 1,5-cyclooctadiene, L L = ethylenediamine, Y = Cl; diene = norbornadiene, L L = 2,2′-bipyridyl, phenanthroline, Y = Cl; M = PtII, diene = 1,5-cyclooctadiene, L L = 2,2′-bipyridyl, 1,10-phenanthroline, Y = hexafluorophosphate) is reported. For M = Pd, treatment of the dienyl complexes with hydrochloric acid in methanol gives Pd(L L)Cl2, while for M = Pt the products are Pt(diene)Cl2.
