| abstract | (57) [Summary] [Structure] General formula [Chemical formula 1] [Me is a methyl group, R 1 is an alkyl group, a cycloalkyl group, an aryl group or an aralkyl group, A is an alkylene group, Arylene group, aralkylene group, oligosilanylene group, -R 2 Si-O-SiR 2 - ( wherein R is an alkyl group), -C 6 H 4 -O-C 6 H 4 -, ferrocenylene group, polycarbosilanes of furylene group, thienylene group or a pyridylene group, m and n are respectively 0 or a positive integer, m + n ≧ 1]. This is 1,2,4,5-tetrakis (dimethylsilyl) benzene and the general formula: R 1 -C≡C-A-C≡ It is obtained by reacting C—R 1 bis (acetylene) s in the presence of a platinum compound. [Effects] Novel polycarbosilanes having a step ladder structure containing a rigid skeleton can be obtained from each easily available raw material by a one-step reaction, and their separation and purification are easy. Polycarbosilanes are useful as conductive materials, heat-resistant materials, especially engineering plastics, and those having a high residual rate during high temperature pyrolysis are useful as preceramics. |
