Addition of nitrogen compounds to C-N multiple bonds

Addition of nitrosyl chloride also does not give single products.30 However, it seems to be of practical use for esters of unsaturated alcohols for instance, Pfleger and Landauer31 obtained 65% of 3-chloro-2-(hydroxyimino)-3-phenyl-propyl acetate in this way from cinnamyl acetate  

3-Tetraalkylaziridinescanbe prepared in astonishingly high yields from tetraalkylethylenes by addition of NOCl, reduction by SnCl2, and ring closure by alkali.32
