Reactions of Phenylenedioxytrihalophosphoranes with Arylacetylenes: I. Synthesis and Steric Structure of 2H-Benzo[e][1,2]oxaphosphorin-3-ene Derivatives

Reactions of phenylenedioxytrihalophosphoranes with arylacetylenes yield 2-halo-4-aryl-2H-benzo[e][1,2]oxaphosphorin-3-ene 2-oxides. Formation of the P-C bond and phosphoryl group is accompanied by ipso substitution of the oxygen atom in the benzodioxaphospholane fragment and halogenation of this fragment at the position para relative to the remaining oxygen atom.
