| Summary: | (CH2)2PPh2]2) (15). Compound 15 was produced in the (CH2)2pPh2]2)(dtP)2 (10), and Au[4(CH2)2pph2]l2(MtP)l (II) (CH2)2PPh2l ) 2(dtP)2 (4), Au[@(CH2)2pMe2l)2(MtP)2(6), (CH2)2pPh2l)2(Mtp)Br (8), t AU2([i-CH2)[4- 1. When cyanide ligands have been involved in either the a gold-gold bond The molecular structures of f Au[ii- acyl complex has been reported. NNM and IR spectra supported anti-[AuBr(mtp)[4-(CH2)2pPh2l 12 (7), Au[4 characterized derivatives of 1. The synthesis of a new gold compared to each other and to other structurally determination of the mixed-valence complex cis-AuAuBr2[4 halide derivatives of I was completed with the structural have been obtained by X-ray crystallography. The structural Homovalent and heterovalent derivatives of the gold ylide involved the reduction of the gold atoms and the formation of isomenzation, and single-center reductions may all be metallocycle (Au[4(CH2)2PPh2l ) 2(l) have been synthesized. methylenediphenylthiophosphinate (mtp) and diphenyldithio observed. The series of structural isomers possible for the occurring due to the presence of cyanide ligands. phosphinate (dtp) have been carried out using dihalide, presence of cyanide ligands greatly affects the chemistry of presence of cyanide. Ligand exchanges, geometrical production of mixed-valence, Au/Au', metallocycles were reactions proceeded as metathesis reactions, while others substitution of halides or in oxidative addition, the Substitution reactions with the potentially bidentate ligands tetrahalide, and A-frame derivatives of 1. Some of these the formation of an asymmetrical Au'-Au' metallocycle. The trans influence on the Au-Br bond lengths of 7 and 8 were |
