Pd(II)-catalyzed intramolecularaminocarbonylation of olefins bearing many types of nitrogen nucleophiles has been examined under two typical conditions: acidic conditions [conditions A, typically PdCl(2) (0.1 equiv) and CuCl(2) (3.0 equiv) under 1 atm of CO at room temperature in methanol] and buffered conditions [conditions B, typically PdCl(2) (0.1 equiv) and CuCl(2) (2.3 equiv) under 1 atm of CO at
The Wacker-typeaminocarbonylation of unsaturatedamides shows distinctive dependence of reactivity on the reaction medium: endo nitrogen nucleophiles (endo-carbanates3 and -ureas 5) undergo aminocarbonylation either in neat methyl orthoacetate (MOA) or in methanol containing AcONa and MOA, while exo nitrogen nucleophiles (exo-carbamates1a, -ureas 1b, and -sulfonamides 1c) in methanol (cat.
