摘要

We now report that direct carbamoylation of aryl iodides, bromides, and chlorides can be carried out by employing carbamoylsilane 1 8 and one of several palladium catalysts (eq 1). A series of haloarenes have been examined under standard conditions involving a 1.0:1.1:0.02 molar ratio of ArX:1:Pd catalyst in toluene at 100 °C and results for aryl bromides are shown in Table 1. 9 Under catalysis by tetrakis(triphenylphosphine)palladium(0) (A), all unhindered ...
