PURPOSE:To obtain the titled compound useful as an intermediate of insecticide, phospholipid, and organic synthetic chemicals, at a high rate of reaction, by reacting a diorganophosphoroimidazolide compound, etc. with an alcohol in the presence of an organotin alkoxide compound. CONSTITUTION:The objective compound of formula II is prepared by reacting (A) the diorganophosphoroimidazolide compound or diorganophosphoro-1,2,4- triazolide compound of formula I (R<1> and R<2> are alkyl or aryl; X is imidazolyl or 1,2,4-triazolyl) with (B) an alcohol of formula HOR<3> (R<3> is primary or secondary alkyl, alkenyl or cycloalkyl) in the presence of an organotin alkoxide compound of formula R<4>3SnOR<5> (R<4> is alkyl or aryl; R<5> is tert-alkyl or 1-substituted-cycloalkyl) [e.g. trimethyl(t-butoxy)-stannane, etc.]. |
