| 1 | Silica-bonded N-propyl sulfamic acid as an efficient recyclable catalyst for the synthesis of 3,4-dihydropyrimidin-2-(1H)-ones/thiones under heterogeneous conditions显示文摘Silica-bonded N-propyl sulfamic acid(SBNPSA) catalyzed one-pot three component Biginelli condensation of different substituted aromatic aldehydes with ethyl acetoacetate and urea/thoiurea to the respective 3,4-dihydropyrimidin-2-(1H)-ones and thiones in environment friendly procedure is described. The facile reaction conditions, simple isolation and purification procedures of this method make it a good option for the synthesis of dihydropyrimidinones. | Srinivasa Rao Jetti Anjna Bhatewara Tanuja Kadre Shubha Jain | 2014 | Chinese Chemical Letters2014，25，3： | 3 |
| 2 | Highly-selective Pt/PAA@MIL-125 Catalyst for Hydrosilylation of γ-(2,3-Epoxypropoxy) Trimethoxysilane显示文摘γ-(2,3-Epoxypropoxy)trimethoxysilane is a crucial silicone product synthesized by hydrosilylation.Its derived downstream silicone products have galvanized the development of silicone industry.However,the Speier's or Karstedt's catalysts commonly utilized in its industrial process are homogeneous,leading to complications,such as low catalytic selectivity and recycling difficulty.Herein,a new heterogeneous platinum catalyst was developed by using a titanium-based metal organic framework(MIL-125)composite with polylactic acid(PAA)as the support.The as-synthesized Pt/PAA-2@MIL-125 catalyst exhibited impressive catalytic performance,producing a 97%yield inβ-product,and maintained recyclability for the synthesis ofγ-(2,3-epoxypropoxy)trimethoxysilane.Further characterization analyses revealed that the introduction of PAA resulted in the formation of a defective mesoporous MIL-125,which accelerated the transmission efficiency of reactants.Moreover,the abundant carboxylic acid groups in the MIL-125/PAA composite could interact strongly with Pt active species,thereby enhancing the catalytic performance and minimizing the loss of Pt,ultimately improving its cycling performance.The comprehensive experiments demonstrated the potential of this catalyst as an effective and versatile heterogeneous catalyst not only for the hydrosilylation of various olefins,but also for the hydrosilyation of silanes. | ZHU Yahui LUO Yanping ZHU Fangyu LIANG Qiuhong YUAN Mingwei ZHANG Bingzhen SHI Shunli WANG Shuhua CHEN Chao | 2023 | Chemical Research in Chinese Universities2023，39，6： | 0 |
