Synthetic Route to Fluoroalkylselenylchalcogeno Molecules

In order to obtain new molecules with specific properties, the design of new fluorinated emerging group is an interesting approach. Herein, the development of new fluorinated motifs is described by associating fluoroalkyl groups with selenium and another chalcogen. Such compounds are obtained by efficient electrophilic fluoralkylselenolations of chalcogen substrates by using two previously described reagents. Thus, molecules bearing R F SeS, R F SeSe and R F SeTe motifs have been obtained with good yields.
