  A New Type of Imido Group Donor:  Synthesis and Characterization of Sulfonylimino-λ³-bromane that Acts as a Nitrenoid in the Aziridination of Olefins at Room Temperature under Metal-Free Conditions

  摘要：

  A stable sulfonylimino-lambda(3)-bromane, CF3SO2N--Br+C6H4-p -CF3, has been syntesized and structurally characterized for the first time. X-ray crystallographic analyses indicated a centrosymmetric dimer structure with little double-bond character for the "ylidic" Br-N bond. THe iminobromane serves as an efficient imido group donor and directly u ndergoes aziridination of olefins stereospecifically of alkenes under transition-metal-free conditions. The observed rate constants for aziridination of cis -cyclooctene are proportional to concentration of the olefin. The results suggest the involvement of a bimolicular transition state, in which an olefin attacks the sigma(*) N-Br orbital of iminobromane in the nitrenoid transfer process.

  Ligand exchange of p-CF3C6H4BrF2 with acetoxy groups using AcOH and Ac2O affords (diacetoxybromo)benzene in a high yield, which undergoes azirldination of alkenes In the presence of TfNH2 and sulfamate esters in one pot under mild conditions. The azirldination with TfNH2 proceeds stereospecifically with retention of stereochemistry of olefins at room temperature using limiting amounts of olefins under transition-metal-free conditions. The one-pot aziridination procedure using sulfamate esters can be applied to the Intramolecular versions.
