Phosphorus–nitrogen compounds. Part 64. Comparative reactions of spiro and ansa (N/O) cyclotetraphosphazenes with bulky (4-fluorobenzyl) N/N and N/O donor type bidentate reagents: structure, stereogenic properties and cytotoxic activity studies

Abstract

Novel inorganic–organic hybrid multiheterocyclic-spiro and ansa cyclotetraphosphazenes were synthesized. The spectral, crystallographic, and stereogenic properties, and the cytotoxic activities of the compounds were presented.
