METHOD FOR PRODUCING PHOSPHORUS-CONTAINING BUTADIENE COMPOUND

PROBLEM TO BE SOLVED: To provide a method for safely and easily producing phosphorus-containing butadiene compound(s) in high selectivity and in an industrially advantageous way without using any toxic halide. SOLUTION: The method comprises the following process: A reaction is carried out between a hydrophosphorus compound of gneral formula(1):X1X2P(O)H and an acetylene compound of general formula(2):R1(R2R3CH)C(OH)C≡CR4to produce the objective phosphorus-containing butadiene compound of general formula(3):R2R3C=C(R1)-CH=CR4[P(O)X1X2] or general forrmula(4):R2R3C=C(R1)-C[P(O)X1X2]=CR4H. In general formula(1), X1and X2are each an alkyl, cycloalkyl, aryl, aralkyl, heteroaryl, alkenyl, alkoxy or aryloxy. In general formula(2), R1, R2, R3and R4are each H, an alkyl, cycloalkyl, aryl, aralkyl, heteroaryl, alkenyl, alkoxy, aryloxy or silyl. In general formula(3) and general formula(4), R1, R2, R3and R4, and X1and X2are the same as mentioned above, respectively. COPYRIGHT: (C)2005,JPO&NCIPI
