A transition-metal-free direct oxidative trifluoromethylation of unsymmetrical biaryls has been achieved by the simple combination of trifluoromethanesulfinate and phenyliodine bis(trifluoroacetate). The trifluoromethylation is selectively observed in the electron-rich arenes.

A series of symmetrical and unsymmetrical benzyl thioethers have been synthesised using a onepot reaction from benzyl halides and thiourea. This procedure avoids the isolation or handling of malodorous thiols and generates high yields of benzyl thioethers in excellent purity.

In an environmentally friendly protocol, InI was used as a reducing agent for the Se-Se bond to prepare unsymmetrical diorganyl selenides with very short reaction times, mild conditions and excellent yields using (bmim)BF(4) as a recyclable solvent.

During the voltage unbalance, the resulting adverse effects on equipments such as induction motors and power electronic converters and drives on ASDs have been described. It has been observed that during unsymmetrical fault, the input rectifier slips into the single phase operation and draw heavy currents which may actuate the overload protection and trip the ASDs. The application of supercapac...
