Abstract
The present invention is related to a process in which an oxazolidinone is reacted with phosphorus pentachloride and the resulting mixture is reacted with a nucleophilic agent in an inert solvent to give P-substituted N,N'-bis-(3-oxazolidinyl-2-one)phosphoramides having the general formula ##STR1## where R.sub.1, R.sub.2, R.sub.3, R.sub.4 are each a group selected from among hydrogen, C.sub.1 -C.sub.4 alkyls or an aromatic nucleus and X is a group which may be introduced by nucleophilic substitution. The invention is also related to the compounds thus obtained.
Claims3
P-substituted N,N'-bis-(3-oxazolidinyl-2-one) phosphoramides of the Formula (I) ##STR17## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent a group selected from among hydrogen, alkyls having from one to four carbon atoms or an aromatic nucleus and X is halogens.
