Suzuki Coupling in LC Synthesis - PowerPoint PPT Presentation

Webthe coupling, except reactive chlorides, such as allylic and benzylic deriva-tives. Heteroaromatic halides can be also used as coupling partners. Ortho-substituents on the benzene ring do not cause difficulty. Thus, the cross-coupling reaction is used for the synthesis of benzo-fused heteroaromatic compounds (Eq 4) (Satoh et al., 1987). Web25 lug 2014 · Suzuki Coupling. Mechanism of Suzuki Coupling. Gabriel Synthesis Notice that the phthalimide moiety serves as a ‘protected’ form of ammonia. The phthalimide carbonyls increase the acidity of the nitrogen (thus allowing formation of its conjugate base) Most importantly, the phthalimide carbonyls protect the nitrogen form ‘over alkylation’ … botapp
