For the first time, chiral imidazolium ionic liquids containing one chiral carbon (10a-c) were synthesized from the natural amino acids by a simple and straightforward procedure. The characteristics of the chiral ILs are very similar to the popular ionic liquids.

An efficient and convenient approach to construct C-C bonds at the 2-position of azoles via Cu(OAc)(2)/air mediated oxidative homo- and cross-coupling reaction was reported. The corresponding products were obtained in good to excellent yield.

A metal-free very highly efficient and concise oxidative-coupling reaction promoted by 2,3-dichloro-5,6-dicyanoquinone (DDQ) between diarylallylic sp 3 C À H and active methylenic sp 3 C À H bonds is reported. The corresponding products are obtained in good to excellent yields.

Dehydrogenative cross-coupling reaction of primary anilines, secondary anilines, carboxamides, and sulfonamides with 1,3-diarylpropenes to form a series of allylic amines promoted by DDQ have been realized. Both monoallylation and diallylation products can be selectively synthesized when primary anilines are used as the starting materials. The method may provide a wide scope of allylamines in scientific research including biologically active compound library construction.
