A general protocol for iridium catalyzed direct C?H amidation of cyclic N-sulfonyl ketimines using sulfonyl, acyl and aryl azides as nitrogen source is reported herein. The reaction takes place at room temperature with acyl and aryl azides, while an elevated temperature needed with sulfonyl azides to furnish aminated sultams in excellent yields with complete chemo and regioselectivity, thus providing a robust and environmentally benign process to the synthesis of aminosultams.

A nondirected amidation reaction of aromatic C-H bond was developed under iron(II) catalysis, using sulfonyl azides as the nitrogen source. The reaction displayed a broad substrate scope and good regioselectivities in the aspects of aromatic ring vs alkyl

Visible-light-induced cross-coupling of arylsulfonyl azides with tertiaryamines in the presence of Eosin Y at room temperature has been achieved. This transformation features alkyl C-C bond cleavage and provides a green approach to N-sulfonylamidines under mild conditions.
Evaluation of dipole moment and electrophilicity on the nature of click-type coupling reaction between thioamide and sulfonyl azide

A cooperated experimental and computational investigation on sulfonyl amidine formation from thioamides and sulfonyl azides is described. The data support a non-concerted two-step pathway for the coupling reaction and also indicate that dipole moment of t
