Abstract
Procedure for the preparation of compounds of the formula **(See formula)** in which R1 is a lower alcohol group possibly substituted by chlorine or a phenyl group optionally substituted by halogen or lower alcohol, or is the group R-0-; where R means an alcohol radical with 1 to 12 carbon atoms, which can be interrupted by oxygen or can be substituted with the group -COOR'(where R' is equal to a lower alcohol), or means an alkenyl radical with 3 to 12 carbon atoms; R2 represents a lower alcohol group and X, Y and Z, which may be the same or different, designate hydrogen, chlorine, bromine, iodine, a lower alcohol group or the nitro group, and in which Z can also represent the nitrile group, the acetyl group or the -S (0) nR'' group, in which R'' means a lower alcohol radical and n means 0, 1 or 2, characterized in that a corresponding diphenyl ester of thionophosphonic acid is transesterified in the presence of bases of the formula **(See formula)** with the alcohol of the formula R2OH (Machine-translation by Google Translate, not legally binding)
