Displacement of ethylene from bis(triphenylphosphine)(ethylene)platinum(0) by four different butatrienes led to four new π complexes. In contrast to known butatriene complexes, the IR, 1H NMR, and 31P NMR spectra of these platinum compounds clearly show that the metal is bound to a terminal unsaturation of the triene. The π-bonding nature of the ligand attachment is indicated by the fast atom bombardment mass spectra and also ligand exchange reactions involving maleic anhydride. Attempts to produce binuclear platinum complexes were unsuccessful, but the platinum fragment may be replaced by rhodium upon reaction with Wilkinson's catalyst. These results are discussed in detail.
