Abstract

Cationic gold(I) complexes of phosphaalkynes are formed by the interaction of [PtBu2(o-biphenyl)AuCl] with AgSbF6 and an excess amount of RC≡P in CH2Cl2 at room temperature. Free and coordinated phosphaalkyne readily exchange through an associative mechanism. In the solid state, the phosphaalkyne binds in a π fashion and slips towards the carbon end of the triple bond. The first crystallographically characterised complex of cationic gold(I) and a phosphaalkyne is reported; the phosphaalkyne is readily exchanged through an associative mechanism. The gold binds in a π fashion to the phosphaalkyne and slips towards the carbon end of the triple bond. Copyright © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
