ABSTRACT

Reaction of azaphospholes (L ) [2-phosphaindolizines (1) and I ,3-azaphospholo[S, I-a]isoquinolines (2)] with [η5-(Cp*RhC2L2 (Cp* = pentamethylcycloPentadienyl) and [Ru( η6-cymene)CI2 in 2: I molar ratio in dichloromethane yields mononuclear complexes of the type [Cp*RhCl2 L)].H20 and [Ru(cymene)Cl2( L)].H20. These complexes have been characterized by elemental analysis, FAB mass, IR and NMR (1H and 31p) spectral data. Stereochemistry of these complexes has been discussed based on NMR data. NMR studies reveal adynamic equilibrium between covalent and ionic forms of the complexes derived from 1 in solution.
