, p. 1329 - 1330 (1994)

1-Alkyl-3-phenyl-1,3-benzazaphospholine oxides are efficiently prepared by Parham-type anionic cyclisation of ortho-lithiated N-alkyl-N-diphenylphosphinoylmethylaniline derivatives obtained by sequential treatment of the parent brominated compounds with methyllithium and tert-butyllithium.
