- Process for producing phosphite
-
There is provided a process for producing a phosphite of the formula (I): wherein R1, R2, R4 and R5 each independently represent a hydrogen atom, a C1-8 alkyl group, a C5-8 cycloalkyl group, a C6-12 alkylcycloalkyl group, a C7-12 aralkyl group or a phenyl group or a phenyl group substituted with an alkyl or an alkoxy group; R3 represents a hydrogen atom or a C1-8 alkyl group; A represents a C2-8 alkylene group or a *—C(═O)— or *—C(═O)—R7— group in which R7 represents a C1-8 alkylene group, and the bond marked with* is the bond connected with the oxygen atom; and one of Y and Z represents a hydroxyl group, a C1-8 alkoxy group or a C7-12 aralkyloxy group and the other one represents a hydrogen atom or a C1-8 alkyl group.
