Dimethyl 2-(methylamino)benzoylphosphonate has been prepared by the
thermal decomposition of dimethyl
2-(N-tert-butyl-N-methylamino)
benzoylphosphonate formed by the action of triethylamine on
1-tert-butyl-3-(dimethoxyphosphinyl)-1-methyl-2,1-
benzisoxazolinium hexafluorophosphate. The reactions of both
benzoylphosphonates with trimethyl phosphite proceed via
carbene intermediates 4 to initially give ylidic phosphonates 5, which
for 5 (X = 2-MeNH) undergoes cyclisation and rearrangement
to give the novel 2-oxophosphorindoline 11.
