The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Tris(triphenylphosphine)chlororhodium, is researched, Molecular C54H45ClP3Rh, CAS is 14694-95-2, about Transition metal-catalyzed hydrosilylation of polybutadiene – The effect of substituents at silicon on efficiency of silyl functionalization process, the main research direction is platinum rhodium complex catalyst polybutadiene hydrosilylation.Synthetic Route of C54H45ClP3Rh.
Herein we present the results of our studies on the hydrosilylation of polybutadiene with alkyl, aryl and alkoxysilanes in the presence of platinum and rhodium complexes. In order to select the most efficient catalytic system, which, under optimal conditions, would smoothly promote incorporation of the above-mentioned organosilicon modifiers into polybutadienes of various structures via hydrosilylation, the real-time in-situ FT-IR spectroscopy was used. The silyl-functionalized polymeric products were characterized by NMR anal. and gel permeation chromatog. (GPC). It was demonstrated that the stereo-electronic properties of substituents directly bonded to the HSi moiety play a crucial role in formation of desired products, as well as affect the time required for total conversion of organosilicon reagents. Partially modified polymers containing pendant alkoxy groups can be applied as additives to rubber compounds to enhance dispersion of inorganic particles in the polymer matrix, as well as to promote formation of organic-inorganic hybrid materials.
