PROBLEM TO BE SOLVED: To provide a new allene derivative and its production method. SOLUTION: A pure allene derivative free from substituent on the terminal, having added malonic acid ester and expressed by formula (1) (R1 is a 1-8C straight-chain alkyl, a branched alkyl-carbon compound having secondary or tertiary carbon, allyl group, an aromatic hydrocarbon group, 1,2-butadienyl group or 2,3-butadienyl group) can be synthesized by using 2-chloro-1,3-butadiene which is a diene compound easily available as a starting raw material and reacting the diene compound with sodium compound of a malonic acid ester using a palladium/phosphine compound as a catalyst. |
