abstract = "New alkylhalogenocyclophosphazenes, including those with unsaturated alkyl groups, have been prepared by the interaction of hexachlorocyclotriphosphazene with Grignard reagents and [Bun3PCuI]4, followed by treatment with alkyl halides.",

note = "Funding Information: The mixture was then cooled to 0 OC, the alkyl halide (42 mmol) was added, and a R2' = rearranged side chain. R1 is the same as in the Grignard reagent R1MgC1. The versatility of this synthesis is shown by the Table. Of particular interest is the observation that l-bromobut- 2-ene and prop-2-ynyl bromide react with (2)by a 1,4-addition route behaviour typical of many organo-copper reagent\textasciicircum{}.\textasciicircum{} Thus, although the structure of (2)has not yet been determined unambiguously, its reactivity patterns are compatible with an 'organo-copper'-type intermediate, as suggested in the structure shown.
