Abstract
The rates of displacement of 5-aminoquinoline (5-Aq) and diethyl sulfide (SEt2) from cis-[PtPh2(CO)(L)] (L = 5-Aq or SEt2) by an extended series of aliphatic amines of comparable basicity (pK(a) = 10.6 +/- 0.4) and of widely different steric properties have been measured in dichloromethane solution. The reaction products cis-[PtPh2-(CO)(am)] (1-15) were characterized either as solids or in solution by their IR and H-1 and C-13 NMR spectra. Crystals of cis-diphenyl(pyridine)carbonyl platinum(II) (12) belong to the monoclinic space group P2(1)/n with lattice constants a = 11.756(2) angstromFile in questo prodotto:
