A library of multisubstituted cyclotriphosphazenes – molecular scaffolds for hybrid materials†
Abstract
An effective approach for the syntheses of new di- and hexafunctional cyclotriphosphazenes, based on olefin or silylacetylene hydrosilylation with 4-dimethylsilylphenoxy cyclotriphosphazene derivatives, is reported. All new compounds obtained with high yields and selectivities were isolated and characterized by 1H, 13C, 29Si, 31P NMR and FT-IR techniques.
