The effects of varying the N-group and using different carbenoids are investigated. Excellent cis-stereochemistry is achieved, except for N-carbamates containing aryl groups. Using the mixed carbenoid LiCHICl, the iodide leaving group is selected for cyclisation affording chloroaziridines only, as a cis/trans mixture. More convenient and higher yielding conditions for the preparation of alkyl N-Ts α-iodoaziridines
