Aziridination, nitrilation and hydrogenation of styrene are promoted on Au(111) pre-covered with NHx groups. NH, N and H were formed on Au(111) at 110 K by electron bombardment of condensed ammonia. 2-phenylaziridine is the major product, accounting for 63% of the total styrene conversion; it is attributed to the addition of NH to styrene. In addition, benzonitrile, benzyl nitrile and ethylbenzene are produced due to reactions with adsorbed N and H atoms, respectively. These observations establish a clear guide for the possible application of supported Au catalysts in the future.
