PYROCATECHOL CYCLOPHOSPHATES IN REACTIONS WITH PROTON-CONTAINING NUCLEOPHILES

Nifant'ev, E. E.,Kukhareva, T. S.,Soldatova, I. A.,Matrosov, E. I.

, p. 1209 - 1212 (2007/10/02)

A general principle of the hydrolysis and alcoholysis of cyclophosphates of pyrocatechol and its derivatives is facile ring opening and anomalously facile cleavage of the P-O (P-N) bond to give, in all of the indicated cases, phosphoric acid 2-hydroxyphenyl phosphate.The latter is predetermined by the formation of a hydrogen bond with the participation of the phenolic hydroxy group of the 2-hydroxyphenyl radical.
