Site-selective sequential coupling reactions controlled by "electrochemical Reaction Site Switching": A straightforward approach to 1,4-bis(diaryl)buta-1,3-diynes

Site-selective sequential coupling reactions directed toward bis(diaryl)butadiynes are described. The reaction site could be controlled completely by the on/off application of electricity. The electro-oxidative homo-coupling of terminal alkynes (electricity ON) and the subsequent Suzuki-Miyaura coupling (electricity OFF) afforded bis(diaryl)butadiynes in high yields. The obtained 1,4-bis(diaryl)butadiynes could be converted to a 2,5-bis(diaryl)thiophene derivative, which exhibited blue fluorescence. The Royal Society of Chemistry 2012.
