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

A new strategy for the synthesis of 6‐hydroxyalkyl‐ and 6‐hydroxyaralkyl‐6 H ‐dibenz[ c,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.
