29Si, 31P and, in part, 13C NMR data are reported for N-trimethylsilyl-triorganophosphine imines as well as some siliconsubstituted methoxy and chloro derivatives. The spin-spin splitting pattern of the 29Si{1H} spectra is discussed for disilanes of the type (RR′R″P=N-SiMe2-)2. A qualitative interpretation of 29Si chemical shifts is preferably being based on hyperconjugation rather than a (p-d)n bonding mechanism. The preparation of a series of bis(phosphinimino)silanes and 1,2-bis(phosphinimino)disilanes is described. |
