In the present article, we report on the synthesis and investigation of the hydrosilylation of liquid crystalline compounds with terminal carbon-carbon double bonds in aliphatic tails mediated by complexes of rhodium (I) and platinum (II). New liquid crystalline compounds based on terephthaloyl-bis-4- oxybenzoate with terminal carbon-carbon double bonds in aliphatic tails were synthesized. The introduction in aliphatic tails of polar and light polarizible fragments lead to a decrease of mesomorphogenic ability-resulting compounds. The hydrosilylation of liquid crystalline compounds with terminal carbon-carbon double bonds in aliphatic tails with 1-(1′-arylethoxy)-1,1,3,3-tetramethyl disiloxanes mediated by complexes of rhodium (I) and platinum (II) was investigated. The main process in these conditions was the isomerization of olefin fragments. Copyright Taylor & Francis Group, LLC.

Liquid-crystalline compounds based on terephthaloyl-bis(4-oxybenzoates) with terminal double carbon-carbon bonds in aliphatic fragments were prepared. The introduction of polar and easily polarizable groups into the aliphatic fragments was shown to reduce the mesomorphic capacity. Hydrosilylation of the polyesters catalyzed by rhodium and platinum complexes was studied. The isomerization of the olefin fragment was demonstrated to be the main process.
