Abstract 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. The products formed in these reactions demonstrate substituent control of the reaction pathway. Copolymerization of propenylphenyl alkynlphosphazenes with styrene gives polymers which add dicolbalt hexacarbonyl and undergo a one electron, chemical reversible reduction.
