Reactions of phenylenedioxytrihalophosphoranes with arylacetylenes: VII. Reaction of 2,2,2-trichloro-4-fluoro-1,3,2λ5- benzodioxaphosphole with phenylacetylene

2,2,2-Trichloro-4-fluoro-1,3,2λ5-benzodioxaphosphole reacts with phenylacetylene to give 2,7-dichloro-5-fluoro-4-phenyl-2H-1, 2λ5-benzoxaphosphinine 2-oxide. Hydrolysis of the latter leads to opening of the oxaphosphinine ring with formation of (E)-2-(4-chloro-2- fluoro-6-hydroxyphenyl)-2-phenylethenylphosphonic acid.
