The preparation of (tht=tetrahydrothiophen) by oxidation of with is described.Displacement of tht by other neutral or anionic unidentate ligands leads to the synthesis of or Q .The compound adds amines to give the gold(III)-carbene complexes > (NR2=NHC6H4Me-p, NEt2, or NHCH2CH2NH2).The reaction of the compound with potentially bidentate ligands takes two different courses. (a) o-Phenylenebis(dimethylarsine) (pdma) and 1,2-bis(diphenylphosphino)methane (dppm) give four-co-ordinated complexes, in which the ligands are unidentate; the pdma complex has inequivalent methyl hydrogens at low temperature (1H n.m.r.) and the dppm complex inequivalent P atoms (31P n.m.r.).An X-ray structure of the pdma complex confirms four-co-ordination in the solid state; space group P21/n, a=10.796(3), b=17.347(6), c=16.275(5) Angstroem, β=94.47(3) deg, Z=4, R=0.058 for 3357 reflections. (b) 1,2-Bis(diphenylphosphino)ethane (dppe) acts as a bridging ligand leading to the formation of .Similar reactions starting from lead to the compounds or The arylation of (1-) or (1-) with Ag(C6F5) leads to (1-) and (1-) respectively.
