Shibasaki catalysts are a class of hetero-bimetallic complexes with the general formula (HREF="http://www.kotoba.ne.jp/word/11/binol" TITLE="binol">binol)3(M)3 ) (M = alkali metal, Ln = lanthanide). They are named after Masakatsu Shibasaki, whose group first developed them, and are used as asymmetric catalysts. ==Development== The Shibasaki group produced the first chiral lanthanide-binaphtholate complex in 1992, which was used to catalyse nitroaldol reactions. The complex was not characterised but was the first to perform the reaction enantioselectively. This success led to further research which resulted in the development of heterometallic complexes with the formula (), the structure of which was elucidated by X-ray crystallography.
