Hydroxylamine O-benzyl ether as an ammonia equivalent in the catalytic amination of aryl halides

The palladium catalysed amination of aryl bromides with hydroxylamine O-benzyl ether leads to the formation of diaryl or triarylamines depending on the size of the aryl bromide, the number of equivalents used or the conditions employed.

Hydroxylamine O-benzyl ether acts as an effective ammonium surrogate in the amination of aryl bromides.
