Abstract

PMR parameters of some methylene substituted oxiranes are obtained from INDOR experiments on the ABXMN spin systems. Compounds investigated include safrol‐ and bromosafrol epoxide and β‐phenoxypropylene oxide. For the latter compound all the relative signs (except for some long range couplings) were obtained and certain of these are in contradiction with those reported ^2^ in β‐chloropropylene oxide. ‘Non‐classical’ long range coupling

is also noted and differs in pathway from that reported previously.^2^.
