Synthesis of β-amino acid derivatives by nickel(0)-mediated sequential addition of carbon dioxide and dibenzoyldiazene onto unsaturated hydrocarbons

A stoichiometric amount of nickel(0) complex mediated the aminative carboxylation of unsaturated hydrocarbons through oxidative cyclization with carbon dioxide followed by insertion of dibenzoyldiazene into the carbon-nickel bond, giving beta-amino acid derivatives.
