| Popis: |
Unsymmetric diaryliodonium salts (R 1 ≠ R 2 ) are sometimes preferred due to economic and accessibility reasons. Thus it is important to understand and predict which aryl moiety is transferred to the nucleophile, i.e. the chemoselectivity of the process. In metal-mediated reactions, the aryl group with the least steric bulk is transferred. 2 In metal-free reactions, an orthosubstituted aryl group is sometimes transferred preferentially over a less hindered aryl moiety although electronic factors are also important. 5c |
