A facile and general synthesis of various N-substituted cyanamides was accomplished by the Tiemann rearrangement of amidoximes with benzenesulfonyl chlorides (TsCl or o-NsCl) and DIPEA.

CuI-catalyzed reactions of N-alkylamidoximes afforded dihydroimidazoles via sp3 C-H amination. On the other hand, the reactions of N-benzoylamidoximes resulted in sp2 C-H amination to form quinazolinones. The reaction mechanisms could be characterized as a redox-neutral radical pathway including a Cu(i)-Cu(ii) redox catalytic cycle. The Royal Society of Chemistry.
