Use of Wittig reaction for the synthesis of conjugated Aza-BODIPYs and their spectral and electrochemical properties
Autor: Mangalampalli Ravikanth, Angira Koch, Sunit Kumar
Publikováno v: IndraStra Global.
The 2-formyl 1,3,5,7-tetraaryl aza-BODIPY and 2-formyl-6-bromo 1,3,5,7-tetraaryl aza-BODIPY were subjected to Wittig reaction with three different ylides under simple reaction conditions and afforded the conjugated aza-BODIPYs in high yields. The aza
