We have reported that Amberlite IRA900F (Amb-F) is an efficient metal-free catalyst for the activation of Si–N and Si–O bonds and a mild base in a variety of organic transformations under solvent-free conditions, such as the addition of TMSN3 to (E)-2-aryl-1-cyano-1-nitroethenes, nitriles, α,β-unsaturated acids and their esters, and the addition of dimethylsilylketene acetal and ethyl nitroacetate
我们已经报道,Amberlite IRA900F (Amb-F) 是一种有效的无金属催化剂,用于在无溶剂条件下激活 Si-N 和 Si-O 键和各种有机转化中的温和碱,例如添加将 TMSN3 转化为 (E)-2-芳基-1-氰基-1-硝基乙烯、腈、α,β-不饱和酸及其酯,以及将二甲基甲硅烷基乙烯酮缩醛和硝基乙酸乙酯加成到 β-硝基苯乙烯。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
