Alkylgold complexes

A number of substitutions of alkylgold complexes by mercuric compounds have been examined by Gregory and Ingold44. The SE1 substitution of 1-cyano-l-carbethoxypentyl(triphenylphosphine) gold(I) has been described in Chapter 4, Section 2.3 (p. 32) and in the present section those substitutions proceeding by bimolecular mechanisms are discussed. 

Apart from the mentioned Au(III) complexes, a wide range of alkylgold(III) dithiocarbamato compounds of the type R2Au(R2dtc) were investigated 159,160). 

Anionic complexes [R2Au] are present in salts with metal or large quaternary cations, but only a few compounds of this type have been isolated.1,2 Solutions of the lithium salts generated in situ are substrates for addition reactions with alkyl halides leading to alkylgold(m) compounds.26... 

An equilibrium is set up when alkylgold(I) complexes are mixed with halide-containing organoplatinum(II) species [Eq. (63)] (213). The extent...

Alkyl(triphenylphosphine)gold(l) complexes are stable and exist in solution as monomeric species (Whitesides et al., 1971, 1974), Reductive coupling of //-alkylgold(I) gives the corresponding dimeric alkanes in high yields. A detailed study with the methylgold complex has demonstrated operation of a...
