## Abstract A synthesis of Cβchlorinated analogues of 1,5βdiazaβ2,4βdiphosphorinanβ6βones is described. The Pβchlorophosphine 3, a key compound for all reported substitution reactions, reacts in an unusual way with N,Nβ²βdimethylβN,Nβ²βbis(trimethylsilyl)urea to give the unsymmetrical product 5, the
The title compound 1 was allowed to react with catechol, 2,3-dihydroxynaphthalene, tetrabromocatechol, resorcinol, saligenin, and 3,5-di-tert-butylcatechol in the presence of triethylamine to form compounds 4a-4d and 4f. Whereas the catechol derivative 4a, the naphthol derivative 4b, and the tetrabr
