DETAILS

Description (English)

Application
Complex with an (S,S)-phenyl-linked-binaphthol which promotes a catalytic 1,4-addition of malonate to cyclic and acyclic enones.1 Co-catalyst with CuF-triphenylphosphine in a general catalytic allylation of ketoimines.2
In many asymmetric catalysis applications, glove box and Schlenk techniques should be employed to prevent exposure of the rare earth catalyst to air and moisture, which can be detrimental to the reaction outcome. Solutions of the catalyst should be made using anhydrous solvents and used shortly after preparation.

Description (简体中文)

Application
含 (S,S)-苯基-连接-联萘酚的络合物，可促进丙二酸酯的催化 1,4-加成反应生成环烯酮和无环烯酮。1在酮亚胺的常规催化烯丙基化反应中，与 CuF-三苯基膦共同作为催化剂。2
在很多不对称催化应用中，应当使用手套箱和 Schlenk 技术防止此稀土催化剂与空气和水分接触，因为这两个因素将对反应结果产生不利影响。用无水溶剂配制该催化剂溶液并立即使用。
