The formation of alkenylplatinum(II) complexes by protonation of platinum(0)–acetylene complexes
Abstract
In the protonation of acetylene–platinum(0) complexes of type Pt(ac)(PPh3)2 to give alkenylplatinum(II) complexes, trans-PtX(alkenyl)(PPh3)2, the platinum and the added proton are mutually cis on the alkenyl double bond.
