The reaction of fac- with the unsymmetrical diphosphazane Ph2PN(i-Pr)P(Ph)(DMP) (L) gives the complex fac- (2) in almost quantitative yield.The structure of the complex has been determined by an X-ray diffraction study.The compound reacts with PR3 (where R = Ph, OPh) to give fac- (3a, 4a), which undergoes an intramolecular isomerization to afford mer- (3b,4b).Synthesis of cis- (1) and fac- (2a) and their spectroscopic data are also reported.
