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

by asymmetric synthesis. The XB donorproperty of racemic ferrocenyl iodoalkynes was demonstrated in solution in two benchmark reactions: the Ritter reaction and the benzoxazole synthesis from thioamides. In contrast, the ferrocenyl chalcogenoalkynes were far less active in these reactions. The potential of racemic and enantiopure ferrocenyl iodoalkynes as XB donors was also confirmed by X-ray diffraction

Trifluoromethylselenolated compounds represent an emerging family of products with specific properties. Herein, easy access to α‐trifluoromethylselenyl carbonylcompounds under mild conditions is described, without pre‐functionalization. The method has been extended to elaborated molecules also with good yields. Furthermore, this strategy can be easily extrapolated to other fluoroalkylseleno moieties
Trifluoromethylseleno substituent (CF3Se) is an emerging group, but its direct introduction onto organic molecules is still quite limited and mainly restricted to nucleophilic methods. Herein, we describe a new approach to easily and safely perform electrophilic trifluoromethylselenolation starting from a simple and easily accessible reagent, namely, benzyltrifluoromethyl selenide. This strategy can
