Fluorination, chlorophosphazenes

A great deal of basicity data is available on substituted chlorophosphazenes. None has hitherto been published on fluoro-phosphazenes. A priori, one surmises a greater electron-withdrawing inductive effect for fluorine, which oould be compensated for by the greater potential of fluorine to back-donate by a mesomsric effect. Data is new compared on structurally related chloro- and... 

Fluorination of chlorophosphazenes, especially the trimeric phos-phazene, has been the subject of studies primarily to understand the... 

Addition of fluorine to both cyclotriphosphazenes and linear polypho-sphazenes have been found to yield significant antimicrobial behavior. Linear polyphosphazenes were formed using 4-fluoroaniline using three differing routes. Scheme 4. First, the conventional nucleophilic substitution route emplying poly[bis-chlorophosphazene] yielded the desired polymer in 87% yield. Second, 2,2,4,4,6,6-hexa (4-fluoroanilino)cyclotriphosphazene...
