摘要：
In the reaction of various 2,3-dihydro-1,3,2-benzodiazaphosphorin-4(1H)-ones with perfluorinated alpha-diketones, CF3C(:O)C(:O)R-f, an oxidative addition reaction with concomitant N-alkylation of the CH3(N) atom, and formation of tricyclic phosphoranes was found to take place. In one case no N-alkylation reaction was observed and a perfluoropinacolyl spirophosphorane was formed instead. The course of the reaction mainly depends on the steric demand of R-f and the N-3 substituents of the benzodiazaphosphorinones. (C) 1997 Elsevier Science S.A.
