An unprecedented Pd/Rh cooperatively catalyzed arylalkynation of alkynylsilanes I (X = CH2, CH2CH2, CHMeCH2; R = Me, Ph; R1 = n-pentyl, Ph, 4-MeOC6H4, etc.; R2 = H, 4-Cl, 4-Me, 5-F) with propargylic alcs. R3CCCMe2OH (R3 = Ph, 4-FC6H4, 1-naphthyl, 2-thienyl, 3-pyridinyl, etc.) has been developed to prepare alkynylidene-containing benzosilacycles II. These silaarenes II possess a particular aggregation-induced emission behavior. Mechanistic investigations demonstrated that the relay trimetallic transmetalation plays a pivotal role in governing this transformation. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0Recommanded Product: 61150-57-0).
2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Recommanded Product: 61150-57-0
