Novel Reaction Using Active Species Derived from Imidazolium Salts

本研究的目的是全面了解N-杂环卡宾（NHC）和离子液体（IL）的化学，这些最近受到了广泛的关注，但已经独立研究。在本研究项目期间，我们成功地发现了一种新的催化不对称三组分偶联反应的1，3-二烯，醛，硅烷使用手性NHC镍配合物。此外，我们还建立了两个铑催化的环化反应，其中催化剂可以在几次循环，使用IL作为反应介质。

The objective of this research is comprehensive understanding of the chemistry of N-heterocyclic carbenes (NHCs) and that of ionic liquids (ILs), those have recently received much attention but have been independently studied. During the term of this research project, we have succeeded in finding a novel catalytic asymmetric three-component coupling reaction of 1,3-diene, aldehyde, and silanes using a chiral NHC nickel complex. And, we have also established two Rh-catalyzed cyclizations, in which catalyst can be recycled in several times, by using IL as a reaction medium.
