Compounds of the formula ##STR1## are phosphorylating reagents which react with acylatable hydrogen atoms with elimination of the amine HNR 3 R 4 . The resulting compounds are oxidized to give the corresponding phosphate, thiophosphate or selenophosphate derivatives, and the radicals R 1 and R 2 are then split off by means of bases. The chemical nature of the radicals R 1 , R 2 , R 3 and R 4 accordingly depends on the requirements for these cleavage reactions. |
