A Pt(0) complex with cyclic (alkyl)(amino)silylene and 1,3-divinyl-1,1,3,3-tetramethyldisiloxane ligands: synthesis, molecular structure, and catalytic hydrosilylation activity
A platinum(0) complex bearing a cyclic (alkyl)(amino)silylene and a 1,3-divinyl-1,1,3,3-tetramethyldisiloxane (DVTMS) was synthesized and isolated in the form of colorless crystals. The single-crystal X-ray diffraction analysis of this complex in combination with theoretical calculations indicated that the Pt→Si π-back-donation in this complex is weaker than that in the corresponding cyclic-dialkylsilylene-ligated

report the development of the first graphene-supported platinumcatalyst that has demonstrated exceptional catalytic activity and stability for hydrosilylation reactions of olefins (TOF 4.8 × 106 h−1, TON = 9.4 × 106). The catalyst also exhibited functional group tolerance over a broad range of industrially relevant substrates with minimal metal leaching. In addition, the catalystsystem was successfully
本文中,我们报道了第一个石墨烯负载的铂催化剂的开发,该催化剂已证明对烯烃的氢化硅烷化反应具有出色的催化活性和稳定性(TOF 4.8×10 6 h -1,TON = 9.4×10 6)。该催化剂还具有广泛的工业相关底物,并且具有最少的金属浸出,对官能团具有耐受性。此外,该催化剂体系已成功转化为用于连续氢化硅烷化反应的填充床平台。
