Abstract:
1. A process for the production of compound(s) represented by the formula [III] and/or the formula [IV] (R 1 , R 2 , R 3 and R 0 4 are the same as those defined below), characterized in that, a catalyst containing a metal of group 9 or group 10 of the periodic table is used and an acetylene compound represented by the formula [I] (in the formula, n is 1 or 2; R 1 and R 2 each when n is 1 and R 2 when n is 2 is hydrogen atom, an optionally substituted alkyl group, an optionally substituted cycloalkyl group, an optionally substituted alkenyl group, an optionally substituted cycloalkenyl group, an optionally substituted aryl group, an optionally substituted aralkyl group, an optionally substituted aryloxy group, an optionally substituted heteroaryl group, a ferrocenyl group, an optionally substituted alkoxy group or an optionally substituted silyl group; and R 1 when n is 2 is an optionally substituted alkylene group, an optionally substituted cycloalkylene group, an optionally substituted alkenylene group, an optionally substituted cycloalkenylene group, an optionally substituted arylene group, an optionally substituted aralkylene group, an optionally substituted arylenedioxy group, an optionally substituted heteroarylene group, a ferrocenylene group, an optionally substituted alkylenedioxy group or an optionally substituted silylenedioxy group) is made to react with a compound represented by the formula [II] [in the formula, R 3 is an alkyl group, a cycloalkyl group, an aralkyl group or an aryl group and R 0 4 is R 4 or OR 4 (where R 4 is an alkyl group, a cycloalkyl group, an aralkyl group or an aryl group)].
