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-benzisoxazoli
Reactions of Anthranilium Salts with Nucleophiles: Adduct Formation and Rearrangement

3-Unsubstituted anthranilium salts 1 react with alcohols in the presence of bases to yield adducts 5 which rearrange to the esters 4 when refluxed in xylene.Similar processes involving 1 and cyanide or azide also have been observed.Evidence favoring benzoazetinones 2 as rearrangement intermediates is presented.The chemistry of 1 with phosphines and phosphites is also described.For example, treatment of 1c with trimethyl phosphite yields the rearranged adduct salt 14 which cleaves to the acyl phosphonate 15 when treated with triethylamine.
