Several new phosphorylated aziridines of related structure were prepared. P.m.r. analysis via decoupling experiments provided cis H‐H, trans H‐H, gem H‐H and PNCH coupling values. Similar to simple aziridines, the cis H‐H coupling is larger than trans H‐H coupling (on vicinal ring carbons) which in turn is larger than gem H‐H coupling. In one example operating at 100 MHz and 0° it was possible to detect the presence of two invertomers.
