METHOD FOR PREPARING 2-HALO-1,3-DIENE FROM ALLENOL USING NO CATALYST AT A HIGH YIELD |
摘要 |
PURPOSE: Provided is a method for preparing various types of 2-halo-1,3-diene compounds from allenol with ease by a simple process using no catalyst at a high yield. CONSTITUTION: The method for preparing a 2-halo-1,3-diene represented by formula 3 from an allenol represented by formula 2 comprises treating the allenol with an indium(III) halide salt represented by the formula of InX3 (wherein X is Cl, Br or I), through the reaction route as depicted in the following formula 4. In formulas 2 to 4, each of R1 to R4 represents H, Si, a halogen atom, an alkyl group, an aromatic substituent or a cyclic substituent. In the method, the reaction solvent is selected from acetonitrile and benzene.
