SiliaCat TEMPO 催化剂

SiliaCat TEMPO is a heterogeneous catalyst/reagent made from a proprietary class of organosilica-entrapped radicals suitable for the selective oxidation of delicate substrates into valued carbonyl derivatives. The leach-resistant organoceramic matrix makesSiliaCatTEMPO highly efficient and selective compared to homogeneous TEMPO reagents and has a superior performance compared to polymer supported TEMPO and to silica supported TEMPO in terms of both selectivity and stability.SiliaCatTEMPO is an effective and useful oxidizing catalyst for delicate primary and secondary alcohol substrates into valued carbonyl derivatives.SiliaCat TEMPO can be used for solid-state synthesis in which no contamination of the product and high selectivity are required. SiliaCatTEMPO is an effective and useful oxidizing catalyst that presents unique advantages.

SiliaCat TEMPO是一种非均相催化剂，是将TEMPO 官能团键合在有机硅上，能够有选择地将特定官能团氧化成羰基。SiliaCat TEMPO相对于均相的TEMPO催化剂，容易在体系中被过滤掉，相对于聚合物键合的TEMPO，具有更高的负载量，有更合适的反应速度，有更好的稳定性和选择性。SiliaCat TEMPO可以将一级醇和二级醇氧化成羰基，SiliaCat TEMPO在固相合成中是一个没有污染，具有高选择性，高效率的十分独特的催化剂。
TEMPO：2,2,6,6-四甲基哌啶-1-氧自由基，是醇氧化成醛或者酮常用的催化剂。
