2H-Benzo[e]-1,2-oxaphosphorine Related Heterocycles as Precursors for the Synthesis of Unsymmetrical Bicyclic Phosphonates

The reaction of 2-hydroxy-5,7,8-trimethyl-2-oxobenzo[ e ]-1,2-oxaphosphorine with thionyl chloride yielded the pyrophosphonate product, which was isolated and characterized for the first time. Subsequent treatment of it with phosphorus pentachloride led to the formation of new types of unsymmetrical...

Description
Summary:The reaction of 2-hydroxy-5,7,8-trimethyl-2-oxobenzo[ e ]-1,2-oxaphosphorine with thionyl chloride yielded the pyrophosphonate product, which was isolated and characterized for the first time. Subsequent treatment of it with phosphorus pentachloride led to the formation of new types of unsymmetrical cage phosphonates.
