Graphical Abstract
  • –N, P–N, and N–H bond-forming reactions. Several studies have proposed copper nitrenoid intermediates originating from dioxazolones, involving an N-acyl nitrene transfer or hydrogen atom transfer process, representing creative synthetic solutions that were previously unachievable using conventional

Despite the prevalence of acid-activation in promoting carbon [28], oxygen [29][30], sulfur [31], chlorine [32], and fluorine [33] transfer reactions of hypervalent iodine compounds, these strategies have not been applied to activation of iminoiodinanes for nitrene transfer chemistry. We
  • Discussion Treatment of cyclohexene (1a) with a stoichiometric amount of simple iminoiodinane such as PhINTs (2a) in CH2Cl2 resulted in <10% conversion to the corresponding N-sulfonylaziridine 3a, which is consistent with the previously reported need for transition metal catalysts to promote nitrene transfer

Graphical Abstract
  • anodically generated nitrene equivalent was transferred to a broad range of olefins using readily available N-aminophthalimide (Scheme 22) [67][68]. In contrast to conventional olefin aziridation, which is typically accomplished via metal-catalyzed nitrene transfer to the C–C-double bond, the electrochemical

Graphical Abstract
  • commercially available phosphoryl chlorides, have been recently explored as nitrene sources for transition metal-catalyzed nitrene transfer reactions [20][21][22][23]. Their use in a catalytic asymmetric aziridination would provide an attractive approach for the synthesis of valuable chiral phosphorous
