A family of novel ionicliquid with l-alanine and choline chloride as environmentally benign materials have been synthesized and grafted on Fe3O4 nanoparticles using easy preparation techniques. The structure of ionicliquid supported on Fe3O4 nanoparticles (IL-Fe3O4 NPs) characterized by various analyses such as FE-SEM, EDX, XRD, NMR, FTIR and VSM. The catalytic activities of this catalyst are examined

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

good yields via a one-pot ring closing reaction, followed by esterification. The methylene bridged bisimidazolium iodide salts are accessible in moderate yields. Corresponding palladium(II)- and platinum(II)-NHC complexes could be synthesized and fully characterized, but do not show optical activity. We also report a solid state structure of one of the synthesized palladium(II) biscarbene compounds derived
