Nuclear magnetic resonance spectra of some silyl and trimethylsilyl pseudohalides

摘要: Proton, 13C, 15N, and 29Si n.m.r. spectra have been recorded for SiH3(CN), SiH3(NCY)(Y = O, S, or Se), SiMe3(CN) at room temperature below, as has the 77Se spectrum of SiH3(NCSe). The show no sign presence other isomers, nor any intermolecular exchange that is fast on time scale. parameters are given, together with T1 nuclear Overhauser enhancement measurements, three different temperatures. spin-rotation contribution to relaxation appears be dominant.
