Solvent-Dependent Cyclization of 2-Alkynylanilines and ClCF2COONa for the Divergent Assembly of N-(Quinolin-2-yl)amides and Quinolin-2(1 H)-ones

Herein, we present an expedient Cu-catalyzed [5 + 1] cyclization of 2-alkynylanilines and ClCF2COONa to divergent construction of N-(quinolin-2-yl)amides and quinolin-2(1H)-ones by regulating the reaction solvents. Notably, nitrile acts as a solvent and performs the Ritter reactions. ClCF2COONa is used as a C1 synthon in this transformation, which also represents the first example for utilization of ClCF2COONa as an efficient desiliconization reagent. The current protocol involves in situ generation of isocyanide, copper-activated alkyne, Ritter reaction and protonation.

Optoelectronic properties of poly(2,5-dithienylpyrrole)s with fluorophore groups

In this study two new, fluorophore anchored 2,5-dithienylpyrrole derivatives (SNS-Carb, SNS-Flo) were successfully synthesized via click chemistry. Both monomers were subjected to electrochemical polymerization and the corresponding polymers (PSNS-Carb and PSNS-Flo) were thoroughly characterized for their electrochromic properties. PSNS-Carb displayed yellow to blue coloration in 1.31 s with a coloration efficiency of 120 cm2 C-1 whereas PSNS-Flo revealed longer switching time (2.67 s) and lower coloration efficiency (78 cm2 C-1). Coexistence of 3,4-ethylenedioxythiophene (EDOT) with SNS-Carb or SNS-Flo in polymerization media resulted in the formation of novel copolymer films (P1 and P2, respectively) having entirely diverged multichromic, superior optoelectronic properties. P1 revealed a switching time of 1.33 s, with a coloration efficiency of 164 cm2 C-1, whereas P2 exhibited a slower response time (1.87 s) with a lower coloration efficiency (155 cm2 C-1), as in the case of their respective homopolymers. In general, P1 was shown to reveal higher ΔE values which indicate it's more noticeable and vivid color changing nature compared to P2. When the optoelectronic properties of homopolymers were compared with that of their respective copolymers, there was an explicit enhancement of the color pallet, switching time, optical contrast and coloration efficiency.
