Abstract
AbstractA practical approach has been developed for efficient synthesis of unsymmetrical aryl s‐triazines via highly selective sequential Suzuki coupling of cyanuric chloride (2,4,6‐trichlorotriazine) with aryl or vinyl boronic or diarylborinic acids catalysed by 0.1–0.5 mol% Pd(PPh3)2Cl2 under mild conditions. The second and third Suzuki couplings for unsymmetrically trisubstituted aryl s‐triazines could be more practically conducted in one‐pot procedure. An electron‐withdrawing conjugate group at phenyl ring of arylboronic acids was unexpectedly found to completely block the coupling while steric hindrance from an ortho electron‐donating substituent could be overcome.magnified image
