《Pd-Catalyzed Negishi Cross-Coupling of Vinyl Bromides with Diborylmethylzinc Chloride》 was written by Kim, Minjae; Lee, Jun Hee; Cho, Seung Hwan. Recommanded Product: 51364-51-3This research focused onvinyl bromide diborylmethylzinc chloride palladium Negishi cross coupling. The article conveys some information:
Pd-catalyzed crosscoupling of vinyl bromides with diborylmethylzinc halides 1-ZnX. The halide source of 1-ZnX and the choice of a monophosphine ligand are critical to the success of the cross-coupling reactions. Hence, the coupling process proceeds efficiently by using diborylmethylzinc chloride 1-ZnCl in the presence of Pd2(dba)3 as the catalyst along with P(o-tolyl)3 as the ligand, providing various α-borylsubstituted allylboronate esters in good-to-moderate yields. Furthermore, we have also demonstrated that the obtained α-boryl-substituted allylboronate ester can be used as a synthetically useful synthon for the preparation of advanced derivatives The results came from multiple reactions, including the reaction of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Recommanded Product: 51364-51-3)
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is used in the preparation of semiconducting polymers processed from nonchlorinated solvents into high performance thin film transistors.Recommanded Product: 51364-51-3 It is also used in the synthesis of polymer bulk-heterojunction solar sells as a semiconductor.
