Systematic substitution on the cubane nucleus: steric and electronic effects
摘要:
Effective methodology for the synthesis of cubanes with novel substitution patterns is presented. The use of an electron-withdrawing group to accelerate ortho-metalation of amide-activated cubanes is described, as is the effect of the steric bulk of the activating group on the degree of ortho-metalation.
