摘要：

We have developed an efficient amidation of aromatic oximes via C-H bond activation using readily available sulfonyl azides as amidation reagents. This reaction is catalyzed by a base metal catalyst system - MnBr(CO)(5)/[Hmim]OTf. Our method offers excellent chemical yields and regioselectivity with good functional group tolerance. The reusability of MnBr(CO)(5)/[Hmim]OTf system makes it relatively practical for large scale C-H amidations.
