Abstract
There is disclosed a method for effectively producing a silicon-containing pentacyclic compound, wherein the method comprises reacting (a) a 1,2-bis(hydrosilyl)benzene with (b) a cyclic diyne in the presence of (c) a platinum compound. There is also disclosed a method for effectively producing a silicon-containing ladder polymer having a complete ladder structure, wherein the method comprises reacting (a) a 1,2,4,5-tetrakis(hydrosilyl)benzene with (b) a cyclic diyne in the presence of (c) a platinum compound.
