Facile conversion of a cationic MoIV phosphinimato complex into an anionic nitrido-bridged dimer with a bis(trimethylphosphine)iminium counterion
Abstract
[Mo(NPMe3)Cl2(PMe3)3]Cl is formed in 82% yield upon treatment of [Mo(N)Cl3] with four equivalents of trimethylphosphine in CH2Cl2 and rearranges to the nitrido-bridged dimer [(Me3P)2Cl3MoNMoCl3(PMe3)2][Me3PNPMe3] upon standing at room temperature in CH2Cl2; X-ray structural analyses of these compounds are reported.
