The extremely rapid acid-catalysed additions of acetylenes to [Pd2Cl2(µ-Ph2PCH2PPh2)2] and the synthesis of [Pd2Cl2(µ-Ph2PCH2PPh2)2(µ-C[double bond, length half m-dash]CH2)]

Abstract

The addition of acetylenes such as HC[triple bond, length half m-dash]CH, HC[triple bond, length half m-dash]CPh, or MeOOCC[triple bond, length half m-dash]CCOOMe to [Pd2Cl2(µ-Ph2PCH2PPh2)2] to give ‘dimetallated olefins’ is catalysed by traces of acid or methanol but inhibited by a base: the ‘dimetallated olefin’ complex [Pd2Cl2(µ-Ph2PCH2PPh2)(µ-HC[double bond, length half m-dash]CH)] makes an interesting comparison with the vinylidene complex [Pd2Cl2(µ-Ph2PCH2PPh2)2(µ-C[double bond, length half m-dash]CH2)].
