The syntheses of the dicobalt hexacarbonyl complexes, N3P3F6-n(C[Formula: see text]CPhCo2(CO)6)n (n = 1 (3), n = 2 (4)), is reported. The introduction of the organometallic fragment allows for simplification of the NMR spectra and separation of the i

The first examples of dimethylaluminum chloride catalyzed living isobutylene polymerizations are presented. The polymerizations are carried out with conventional tertiary alkyl chloride initiators and 60/40 v/v nonpolar/polar solvent mixtures, the mo

The geminal and nongeminal isomers of N3P3F4(≡ CC6H5)C6H4C(CH3)=2 undergo radical addition polymerization with styrene to produce copolymers having pendant cyclophosphazenes containing a phenylethynl substituent. Reactions of the copolymer derived

In contrast to previously studied reactions of ethynyl lithium reagents, the reactions of propynyl and hexynyl lithium with N(3)P(3)F(6) lead to predominantly nongeminal isomers. A modest cis stereo selectivity was observed. The sequential addition o

A series of alkyl- and fluoroalkyl-substituted polyphosphazenes, [Me(Ph)PN] x (RMe 2 SiCH 2 )-(Ph)PN] y , were prepared by deprotonation of the methyl groups on [Me(Ph)PN] n with n-BuLi, followed by treatment of the intermediate anion with the corres

The P-phenyl ring in poly(methylphenylphosphazene), [Me(Ph)PN] n (1), was nitrated at the meta position using a mixture of nitric and sulfuric acids, producing the nitrophenyl derivatives [Me(Ph)-PN] x [Me(3-NO 2 C 6 H 4 )PN] y (2). Between 10 and 60

The deprotonation-substitution reactions of poly(alkyl/arylphosphazenes) such as [Me(Ph)PN]n have proven to be a simple, one-step method for modification of this class of phosphazene polymers. Recent studies of the anion intermediate produced by depr

The regio- and stereochemical pathways followed in the reactions of the lithioacetylenes, LiC=CR (R=Ph31 Me, n-19Bu), with N3P3F6 have been examined by 31P and 19F NMR spectrscopy. Mixed propenylphenyl, phenylacetylene derivatives were also prepared.
