An. Bovin et al., SYNTHESIS AND STRUCTURE OF 1-SUBSTITUTED 1-OXO-1,2-DIHYDRO-4H-3,1-BENZOXAPHOSPHORINS, Bulletin of the Russian Academy of Sciences, Division of Chemical Sciences, 41(9), 1992, pp. 1704-1708
1-X-1-Oxo-1,2-dihydro-4H-3,1-benzoxaphosphorins (X = CH2Cl, Ph, and OH
) were obtained by reacting ortho-(butoxymethoxymethyl)phenylmagnesium
bromide with derivatives of chloromethylphosphonic and chloromethylph
osphinic acids, followed by intramolecular alkylation. X-Ray diffracti
on was used to study the molecular and crystalline structure of one of
these compounds (with X = OH).
