Abstract

[Au(C6F5)(tht)], which on reaction with P, O, S-coordinating phosphines in CH2Cl2 medium leads to [Au(C6F5)(X)] [X = PPh3 H, (1a), oMe, (1b), pMe, (1c), mMe, (1d), AsPh3 (2), OPPh3 (3), SPPh3 (4), dppm, dppe, dppa = diphenylphosphino-methane,-ethane,-ammine(5, 6, 7), TPA = 135-tetraaza-7-phosphino adamentane(8), Py4H (9a), 4Bu (9b), 4Ac (9c), tht = tetrahydrothiophen, C6F5 is the pentafluorophenyl ring]. The maximum molecular peak of the corresponding molecule is observed in the ESI mass spectrum. I.r. spectra of the complexes show –C = C– and C6F5 stretching near at 1610 and 1510, 955, 800 cm−1. The 1H-n.m.r. spectra as well as 31P- (1H)n.m.r. suggest solution stereochemistry, proton movement, phosphorus proton interaction. 13C-n.m.r. spectrum reflect the carbon skeleton in the molecule. In the 1H–1H COSY spectrum of the present complexes and contour peaks in the 1H–13C-HMQC spectrum, assign the solution structure and stereoretentive conformation in each step.
