Abstract: PURPOSE:To provide the subject compound useful as a synthetic intermediate for a monomer for the synthesis of a side-chain type polymer liquid crystal exhibiting stable liquid crystal nature at a relatively low temperature. CONSTITUTION:A compound of formula I (R and R are alkyl or phenyl; X is single bond, O, COO or OCO; Q is mesogen group; p is 2-20), e.g. 4-(3- methylethoxysilylpropoxy)-4'-cyanobiphenyl. The compound can be produced by reacting an alkenyl compound of formula II (g is 0-18) having a mesogen group (e.g. 4-allyloxy-4'-cyanobiphenyl) with a compound of formula III (R is alkyl) in the presence of a hydrosilylation catalyst and hydrolyzing the resultant compound of formula IV. A side-chain type polymer liquid crystal having siloxane bond on a spacer can be produced by synthesizing a monomer having a mesogen group and a polymerizable group bonded through a siloxane bond using the compound of formula I and polymerizing the synthesized monomer.
