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