The selective mono-N-methylation of anilines derivatives was achieved under mild conditions using inexpensive methanol as C1 source. Under hydrogen borrowing conditions, using a tridentate PN3P manganese pre-catalyst (5mol%), a catalytic amount of base (20mol%), for 24h at 120°C, a large variety of anilines derivatives was methylated in good to excellent yield. Mechanistic investigations allowed us...
