Abstract:

Several alkenylfluorocyclotriphosphazenes have been prepared and characterized. Oligomeric side products obtained in the reaction of propenyl lithium with N3P3F6 result from anionic attack on the propenyl phosphazene. The yield of oligomers is dependent on the grade of lithium used. The mono and disubstituted vinylether derivatives, N3P3F6-n COR CH2m n 1,2 R CH3, C2H5 were prepared from N3P3F6 and the appropriate lithium reagent. Oligomeric side products are not observed. The reaction follows a geminal pathway. Reactions leading to mixed substituent derivatives, N3P3F4XCOC2H5 CH2 X C6H5, NCH32, have been carried out and a directive effect based on the ring substituent has been observed. Copolymerization of N3P3F5COC2H5 CH2 with styrene has been investigated. Nmr 1H, 13C, 19F, 31P spectroscopy studies allowed for both structural characterization and elucidation of charge distribution in the various alkenyl moieties. Author
