|Abstract: ||Disclosed is a process for making certain organo thiophosphates and
dithiophosphates, a number of which have utility as insecticides. The
process comprises effecting by free radical catalysis at about
0.degree.-150.degree.C. reaction of an organic compound characterized by a
saturated carbon with at least one hydrogen replaceable under free radical
conditions, and halo-thiophosphate of the formula:
Wherein X is a halo radical, Z is selected from the group consisting of the
oxo and thioxo radicals, and R and R' are organic radicals.
