Selective hydrosilylation of allyl chloride with trichlorosilane
Autor: Koya Inomata, Yuki Naganawa, Zhi An Wang, Kei Sakamoto, Kazuhiro Matsumoto, Kazuhiko Sato, Yumiko Nakajima
Publikováno v: Communications Chemistry, Vol 4, Iss 1, Pp 1-9 (2021)
Hydrosilylation of allyl chloride with trichlorosilane is industrially important but often proceeds unselectively. Here a Rh(I) catalyst which achieves 99% selectivity on gram scale is described, based on bidentate phosphine ligands.
