Phosphoryl dichloride

This intermediate (or its ethyl homologue), produced dining the preparation of phosphoryl dichloride isocyanate from interaction of phosphorus pentachloride and methyl (or ethyl) carbamate, is unstable. Its decomposition to the required product may be violent or explosive unless moderated by presence of a halogenated solvent. [Pg.283]

A second method that we considered involved condensation of a carbohydrate-derived phosphate salt with an in situ-generated phosphoryl dichloride.21 The requisite phosphoryl dichlorides are prepared via exposure of a lipid phosphate to a Vilsmeier-type reagent. This protocol has been used successfully for the preparation of lipid diphosphate linkages in the dolichol series (i.e., lipids lacking an allylic double bond proximal to the diphosphate linkage). However, we were once again, hesitant to expose our undecaprenyl phosphate precursor to activation conditions that produce HC1 as a by-product. [Pg.302]
