6-Aryl substituted phenanthridines were synthesized via a visible-light-catalyzed cyclization of 2-isocyanobiphenyls with arylsulfonyl chlorides under oxidant-free and transition-metal-free conditions. This transformation represents an efficient and attractive synthetic utilization of arylsulfonyl chlorides.

A visible-light-catalyzed synthesis of aryl ketones from aryldiazonium salts, CO and (hetero)arenes at room temperature is discovered. This transformation represents an efficient and attractive synthetic utilization of aryl diazonium salts.Scheme 1 Synthesis of aryl ketones via redox carbonylation. † Electronic supplementary information (ESI) available.

A visible-light-catalyzed synthesis of 3-acylindoles from simple indoles and α-oxo acids at room temperature has been discovered. This method offers rapid access to 3-acylindoles through C–C and C–H bond activation.

An electrochemical dehydrogenative [2 + 2 + 1] annulation used for the synthesis of imidazoles has been developed under undivided electrolytic conditions.

A rhodium-catalyzed cyanation of chelation assisted CÀH bonds is described. This process provided a useful method for the preparation of diverse 2-cyanated arylphosphonate and related compounds in good yields. The reaction tolerates a variety of synthetically important functional groups.

A new procedure is developed for the synthesis of α-aminophosphonates containing thiazole[5,4-b]pyridine moiety from conveniently available starting materials. The target compounds were characterized by infrared, (1)H NMR, (13)C NMR, (31)P NMR, mass spectrometry and elemental analysis. The newly synthesized compounds were evaluated for their anticancer activities against PC-3, Bcap-37, H460 cells in vitro by the MTT method. Compounds 3b and 3f are highly effective against PC-3, Bcap-37 cells and good to H460 cells. Further study is necessary to find out the potential antitumor activities.

A visible-light-catalyzed synthesis of unsymmetrical 2,3-diaryl-substituted indoles from arylsulfonyl chlorides and o-azidoarylalkynes at room temperature has been discovered. This transformation exhibits excellent substrate scope and functional group tolerance. The use of inexpensive eosin Y as the catalyst with easy operation makes this protocol very practical.
