So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Rivero-Crespo, Miguel; Oliver-Meseguer, Judit; Kaplonska, Klaudia; Kustrowski, Piotr; Pardo, Emilio; Ceron-Carrasco, Jose Pedro; Leyva-Perez, Antonio researched the compound: Dichloro(1,5-cyclooctadiene)platinum(II)( cas:12080-32-9 ).SDS of cas: 12080-32-9.They published the article 《Cyclic metal(oid) clusters control platinum-catalysed hydrosilylation reactions: from soluble to zeolite and MOF catalysts》 about this compound( cas:12080-32-9 ) in Chemical Science. Keywords: platinum zeolite metal organic framework alkyne alkene alc hydrosilylation. We’ll tell you more about this compound (cas:12080-32-9).
The Pt-catalyzed addition of silanes to functional groups such as alkenes, alkynes, carbonyls and alcs., i.e. the hydrosilylation reaction, is a fundamental transformation in industrial and academic chem., often claimed as the most important application of Pt catalysts in solution However, the exact nature of the Pt active species and its mechanism of action is not well understood yet, particularly regarding regioselectivity. Here, exptl. and computational studies together with an ad hoc graphical method show that the hydroaddn. of alkynes proceeds through Pt-Si-H clusters of 3-5 atoms (metal(oid) association) in ppm amounts (ppm), which decrease the energy of the transition state and direct the regioselectivity of the reaction. Based on these findings, new extremely-active (ppm) microporous solid catalysts for the hydrosilylation of alkynes, alkenes and alcs. have been developed, paving the way for more environmentally-benign industrial applications.
