Selective hydrosilylation of Alkynes to obtanin vinyl-silanes using a Pt-NHC complex

Treball Final de Màster Universitari en Química Aplicada i Farmacològica. Codi: SIM138. Curs: 2017/2018The aim of this work is to study the catalytic properties of a platinum molecular complex and the related hybrid material prepared by immobilization of the molecular complex onto reduced graphene oxide by non-covalent interactions. This objective can be divided into the following items: • Synthesis and characterization of an imidazolium salt that would serve as ligand precursor. • Synthesis of a new Pt-NHC complex and full characterization by 1H NMR, APT NMR, COSY, HMBC, HRMS, X-Ray diffraction and TGA • Immobilization and characterization by TEM and ICP-MS of the Pt-NHC complex onto rGO • Study of the catalyst properties of both systems in the hydrosilylation of alkynes. • Study of recyclability of the hybrid material in the hydrosilylation of alkynes. • Study the mechanism of the hydrosilylation of alkynes reactio
