The recyclable metallic imidazolium-based ionic liquid-catalyzed mono-hydroboration of imines, double-hydroboration of imine with aldehyde, and double-hydroboration of aniline with glutaric dialdehyde in the presence of HBpin in water is described for the first time. The ionic liquid [BMIm]­[FeCl4] showed excellent activity, high selectivity, and good recyclability for the catalytic imine hydroborations. This catalytic system widely tolerated various functional rings and unsaturated groups without additional reduction. Furthermore, the metallic ionic liquid [BMIm]­[FeCl4] could be reused for more than 15 runs in water without decay of the catalytic activity.

An efficient and visible light promoted cascade N-alkylation/amidation of quinazolin-4(3H)-ones with benzyl halides and allyl halides has been firstly described to provide a convenient access to quinazoline-2,4(1H,3H)-diones. This cascade N-alkylation/amidation...

A convenient and practical pathway to 2-cyano and 2-ester anilines is described via efficient and selective copper(II) catalyzed reductive amination via hydrosilylation process. Both 2-cyano and 2-ester anilines were successfully synthesized with good functional group tolerance and high selectivity. The application of the 2-cyano and -iodine containing anilines was developed in the synthesis of indoloindole derivatives via CuSO4 catalyzed N-benzylation and cyclization reaction in “one pot”. More interestingly, the photophysical properties investigations of these 2-cyano and 2-ester containing anilines exhibit excellent fluorescent properties which have great potential application in the development of interesting near-ultraviolet optical devices in the near future.
