应用
Lanthanum(III) isopropoxide finds application in asymmetric catalysis. It forms complex with an (S,S)-phenyl-linked-binaphthol ,which enhances a catalytic 1,4-addition of malonate to cyclic and acyclic enones. It acts as a co-catalyst with copper fluoride-triphenylphosphine in catalytic allylation of ketoimines.

备注
Incompatible with strong oxidizing agents and acids.

应用

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。
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。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。
