A divergent visible-light-induced Ph3P-promoted method for the synthesis of ureas and formamides from amines and CO2 is reported. Without external additions, a range of ureas could be directly accessed under ambient temperature and pressure. Using triisopropylsilanethiol as the hydrogen source, formamides could be produced.
