Facile Synthesis of 1,4-Bis(diaryl)-1,3-butadiynes Bearing Two Amino Moieties by Electrochemical Reaction-Site Switching, and Their Solvatochromic Fluorescence

Bis(diaryl)‐1,3‐butadiynes bearing two amino moieties were easily synthesized by a sequential coupling reaction by using an electrochemical method. This sequential reaction consists of electrochemical oxidative homocoupling and Suzuki–Miyaura coupling. The fluorescence of the obtained bis(diaryl)‐1,...

Description
Summary:Bis(diaryl)‐1,3‐butadiynes bearing two amino moieties were easily synthesized by a sequential coupling reaction by using an electrochemical method. This sequential reaction consists of electrochemical oxidative homocoupling and Suzuki–Miyaura coupling. The fluorescence of the obtained bis(diaryl)‐1,3‐butadiynes is solvatochromic despite their symmetric linear structure and lack of a strong acceptor moiety.
