Synthesis of Functionalized Thiophenes for the Preparation of Conducting Polymer Films with Complexing Properties
摘要:
Four series of novel substituted thiophenes (Schiff bases, esters, amides, and amino acids) have been synthesized and tested for their ability to form conducting polymer films via cyclic voltammetry in order to obtain electrochemical sensors for metal cations. The influence of the nature and size of the substituents on the electropolymerizability of the monomers has been studied.

An efficient ruthenium-catalyzed direct C–H selenylation of aryl acetic amides and esters has been achieved via distal weakly coordination. Notable features of this protocol including broad substrate scope, wide functional group tolerance, and good regioselectivity. In addition, diaryl disulfides were also successfully applied to this reaction under slightly modified conditions.

The enantioselective carbene insertion into N–H bonds of anilines has been realized by cooperativecatalysis of ruthenium complexes and chiralphosphoricacids, providing the expected α-aryl glycines in moderate to good yields with high enantioselectivity. Typically, by slightly modifying the reaction conditions, this approach allows the N–H bond insertion reaction to be effective for both α-aryl and
