Patent ID: 8624024

Claim:
A phosphoramide compound represented by general formula (1) or (1′) wherein R 1 is a monovalent hydrocarbon group which is selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an arylalkyl group and an arylalkenyl group, and which may have at least one substituent; R 2 and R 3 independently are monovalent hydrocarbon groups which are selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an arylalkyl group and an arylalkenyl group, which may have at least one substituent; R 2 and R 3 may be bonded to each other to form a ring; R 4 and R 5 independently are monovalent hydrocarbon groups which are selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an arylalkyl group and an arylalkenyl group, and which are bonded to each other to form a ring that may have at least one of an oxygen atom, a nitrogen atom and a sulfur atom in the ring and at least one substituent; X is an oxygen atom or sulfur atom; and B is a methylene group or carbonyl group.
