| Abstract: | NMR studies revealed that the reactions of phenylenedioxytrichlorophosphorane with phenylacetylene and propargyl chloride in the presence of benzyltrimethylammonium chloride predominantly yield derivatives of 2,7-dichloro-2-oxobenzo[e]-1,2-oxaphosphorinine, i.e., the benzene ring is selectively chlorinated in the meta-position to the endocyclic O atom of the phosphorinine heterocycle. |
