Two new thiophosphoramide structures: N,N00,N0000-tricyclohexylphosphoro-thioic triamide and O,O00-diethyl (2-phenylhydrazin-1-yl)thiophosphonate

摘要

Among the results of the P(S)[N]3 search, there are a few reports on the structure determinations of phosphorothioic triamides with a P(S)[N(C)(C)]3 skeleton, for example, [(CH_3)_2N]_3P(S) (CSD refcode NAHWUO; Rudd et al., 1996). However, there is no report of a diffraction study of an [RNH]_3P(S) phosphorothioic triamide. In fact, only one example of a compound with a P(S)[NH]_3 skeleton {and not a P(S)[NH(C)]3 skeleton} was found in the CSD for the structure of [Me_3SiNH]_2P(S)-NH-P(S)[NHSiMe_3]-NH-P(S)[NH-SiMe_3]_2 (CSD refcode ICEDEZ; Pinkas & Verkade, 1998). For the P(S)[O]_2[N] search, the variety of compounds deposited is larger compared with the P(S)[N]_3 skeleton and structures with [O]_2P(S)[N-C(S)] (Babashkina et al., 2011), [O]_2P(S)[N-S(O)_2] (Oltean et al., 2013) and [O]_2P(S)[N-N] (Rybarczyk-Pirek et al., 2006) segments, and some others, were deposited.
