A Novel synthesis of 6-hydroxyalkyl-and 6-hydroxy-aralkyl-6H-dibenz[c,e][1,2]oxaphosphorin 6-Oxides

A new strategy for the synthesis of 6-hydroxyalkyl- and 6-hydroxyaralkyl-6H-dibenzc,e]1,2]oxaphosphorin 6-oxides 3 was achieved by the reaction of 2-(2-hydroxyphenyl)phenylphosphonic acid ( 1 ) with various carbonyl compounds 2 . The desired products 3 were obtained in acceptable yields.
