Gold bond

Novel boron-gold bonds containing complexes are realized in two borido clusters. Addition of [HFe4(CO)i2BH] ppn to xs (PPhjIAuCl in CH2CI2 forms the green-brown, air-sensitive Fe4(CO) 2(AuPPh,)2BH ...

Unlike alkyl-gold bonds the Au—C bonds in pentafluorophenyl compounds are more resistant to cleavage by protic acids, giving more chemical integrity to the complexes.

Although the sulfur-gold bond has been most investigated, the Group 16 elements selenium and tellurium have also attracted attention and are discussed in detail here (polonium has not received attention due to its radioactivity). 

The high tendency of thiols to form sulfur-gold bonds upon oxidation on a gold electrode was used in numerous investigations to modify gold electrodes for different analytical and synthetic purposes.

The topic of molecular transition metal-gold bond-containing compounds, especially of cluster compounds, has developed considerably in recent years (Table 4.6).
