Abstract:
The disclosed compounds include derivatives of 1,2-diphosphacyclopentene-(5)-one-(4) having the formula:
WHEREIN R1 represents an aliphatic, cycloaliphatic, heterocyclic or aromatic radical linked to the nucleus via an oxygen atoms, R2 and R3 each represent aliphatic, cycloaliphatic, heterocyclic or aromatic radicals, which may be linked to the nucleus via a bridge atom A selected from the group of oxygen, sulfur, nitrogen, and phosphorus, n is an integer having a value of 0 or 1 if the bridge atom is oxygen, and if the bridge atom is sulfur, nitrogen or phosphorus n has a value of 0, 1 or 2, and R4, R5 and R6 each stand for a carboxylic acid ester group.
