Cationic Au(I) alkyne complexes: synthesis, structure and reactivity.
Complexes of the type [(Bu(t)(3)P)Au(eta(2)-alkyne)][SbF(6)] can be accessed readily by treatment of CH(2)Cl(2) solutions of the alkyne with [AuCl(PBu(t)(3))]/AgSbF(6); when the alkyne carries one or two Me(3)Si substituents, desilylation reactions can occur leading to species with gold bonding in intricate bonding motifs to the C[triple bond]C fragments.
