Alkenes can be efficiently aziridinated using highly soluble iminoiodane derivatives under continuousflow conditions. By combining the aziridine generation with nucleophilic ring opening reactions, a variety of products can be made without the need to handle or isolate these potentially hazardous intermediates. Additionally, this chemistry can be used to make and use aziridines that are difficult

In this study, hydroxyl functionalized copper(II) Schiff-base; [Cu((OH)(2)-salophen)], [(OH)(2)-salophen] = (N,Ni-bis(4-hydroxysalicylidene) phenylene-1,2-diamine); has been covalently anchored on modified multi-wall carbon nanotubes (MWNTs); [Cu((OH)(2)-salophen)@MWNTs. The new modified MWNTs have been characterized by transmission electron microscopy, X-ray diffraction, thermogravimetric analysis, UV-visible spectroscopy, diffuse reflectance, Fourier transform infrared spectroscopy and elemental analysis. The results suggest that the symmetrical Schiff-base is a bivalent anion with tetradentate N2O2 donors derived from the phenolic oxygen and azomethine nitrogen. MWNTs covalently anchored copper(II) complex catalyze the aziridination of alkenes employing [N-(p-tolylsulfonyl)imino]phenyliodinane (PhI=NTs) as the nitrogen source. (C) 2015 Elsevier B.V.
