Phosphorus‐Containing Heterocyclic Compounds Derived from N‐Vinylpyrroles

C-phosphorylation of N-vinylpyrroles with phosphorus(III) halides is shown to occur both at position 2 of the pyrrole ring and at the vinyl group. The properties of the resulting phosphorus-containing heterocyclic compounds and bis-phosphorylated N-vinylpyrroles are reported. © 1997 John Wiley & Sons, Inc. Heteroatom Chem 8:495–499, 1997
