摘要

The s theses and l6N, 31P, and 13C NMR spectra of a series of N-phenyl-P, PQ- triarylphospha-X6-azenes 4 and the% and 13C NMR spectra of the corresponding series of triarylphosphines 5 and triarylphosphine oxides 6 are reported. The substituent effects on the chemical shifts can be best accommodated and rationalized by use of a model for system 4 whereby the dipole of the aryl group and ita pendant R group polarizes the rest ...
