The synthesis and structural characterization of novel Pt(0) complexes are reported. A number of (NHC)Pt(dvtms) (dvtms = 1,3-divinyl-1,1,3,3-tetramethyldisiloxane) complexes were studied in catalytic addition of B2Pin2 to terminal alkenes. The novel expanded ring N-heterocyclic carbene complex (7-Dipp)Pt(dvtms) showed highest performance, turnover numbers up to 3800 were achieved. The scope of the reaction was illustrated by 20 examples with a variety of alkyl, alkoxy, halogen, ester, ketone and acetal substituents. In the experiment, the researchers used many compounds, for example, 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0Recommanded Product: 258278-25-0)
1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0) may be used as a precursor to the free carbene 1,3-bis(2,6-diisopropylphenyl)-2-imidazolidinylidene, and also used as an in situ formed catalyst in a variety of reactions, e.g. amination, Heck coupling reaction, the ring-opening metathesis polymerization (ROMP), hydrogenation.Recommanded Product: 258278-25-0In addition, it can efficiently catalyze the Suzuki-Miyaura coupling of aryl chlorides with aryl boronic acids.
