Reactions of trialkoxynitridomolybdenum with low-coordinate phosphorus compounds containing a PN double bond†
Abstract
The reactions of NMo(OR)3 (R = tBu, iPr) with (Me3Si)2NPNSiMe3 (1), (Me3Si)2NPNtBu (2), (Me3Si)2NPS(NtBu) (3) and (Me3Si)2NP(NSiMe3)2 (4) have been studied. Reported complexes were synthesized via1,2-addition of an Mo–OR bond across the PN bond, resulting in four-membered metallacycles of the corresponding σ2λ3-iminophosphine or σ3λ5-iminophosphorane with trialkoxynitridomolybdenum. The structure of all new compounds was elucidated by 1H, 13C and
