Synthesis of Chiral Polysiloxane via Hydrosilylation between Synthesized Hydrogen-Containing Polysiloxane and a Chiral Unsaturated Amide

Abstract

In this article, we synthesized some hydrogen-containing polysiloxanes by ring-openging polymerization of cyclosiloxanes and studied their viscosity-average molecular weights (η) and active hydrogen content respectively. Then we prepared a chiral amide compound by condensation reaction of acryloyl chloride and (1S)-1-phenylethanamine. Subsequently, we successfully carried out hydrosilylation reaction with the chiral amide and one of hydrogen-containing polysiloxane. In addition, the structures of the target molecules have been confirmed by IR and 1H NMR spectra, elemental analysis and polarimetric analysis.
