چکیده
Available online-1-n-butyl-3-methylimidazolium selenocyanate ([bmim][SeCN]) proved to be a very efficient reagent for selenocyanation of alkyl halides. As part an eco-friendly process, no organic solvents were used during the transformation and reaction times are reduced by using microwave as heating source. The ionic liquid was carefully recycled in two different ways. Selenocyanate compounds successfully transformed into trifluoromethylselenides one-pot step procedure.

How nucleophilic are diazo compounds?
The kinetics of the reactions of benzhydryl cations with eight diazo compounds 1 a-g were investigated photometrically in dichloromethane. The nucleophilicity parameters N and slope parameters s of these diazo compounds were derived from the equation log k (20 degrees C)=s (E+N) and compared with the nucleophilicities of other pi systems (alkenes, arenes, silyl enol ethers, silyl ketene acetals...

The use of methanesulfonic acid as a Brønsted acid for direct ortho-acylation of phenols and naphthols proves to be a convenient, more general and direct route to various hydroxyaryl ketones. The route is regioselective, leading to ortho C-acylated products in satisfactory to high yields in most cases. The solvent free reactions described below exhibited environmentally benign in terms of faste...
