compounds, (Me3Si)2NP(CCR)2 (1: R=SiMe3; 2: R=n-Bu; 3: R=CH2OCH3), (Me3Si)2NP(Ph)CCSiMe3 (4), and (Me3Si)2NP(R)CCCH2OCH3 (5: R=i-Pr; 6: R=CH2SiMe3; 7: R=n-Bu) were obtained from the reactions of C-lithiated acetylenes LiCCR with either mono- or dichloro substituted (silylamino)phosphines. Similar reactions involving HCCMgCl gave the parent P-ethynyl derivatives, (Me3Si)2NP(R)CCH (12: R=CH2SiMe3;

The reactions of the phosphane [(Me3Si)2N](Ph)PCl with NaCpMo(CO)3 and NaCpW(CO)3 give the respective metallophosphenium complexes Cp(CO)2MP(Ph)[N(SiMe3)2]} (M = Mo (4a), W (4b)). The subsequent reactions of 4a,b with S and Se produce unexpectedly different products: Cp(CO)2(S)MP(Ph)[N(SiMe3)2]} (M = Mo (7a)); Cp(CO)2MSP(Ph)[N(SiMe3)2] (M = W (7b)); Cp(CO)2MSeP(Ph)[N(SiMe3)2] (M = Mo (8a), W (8b))

One approach to the synthesis of polyphosphazenes is the condensation polymerization of phosphoranimines. In this work, several novel P-n-propyl-N-trimethylsilylphosphoranimines have been synthesized and characterized. Modifications to the literature synthetic routes were required to obtain the precursor phosphines. The N-trimethylsilylphosphoranimines were obtained though oxidation of the phosphine with bromine and then subsequent nucleophilic displacement using lithium phenoxide. These phosphoranimines were stable for long periods of time under dry inert conditions. NMR analyses revealed complex splitting patterns beyond typical coupling due to the stereocenter at phosphorus. We report several approaches to the n-propyl containing phosphines and phosphoranimines.
