Spectroscopic studies of some ethylene oxides

ABSTRACT

Z- and E-1,2-di-[4-nitrophenyl]-1-phenyl-ethylene oxides I and II were prepared by the reaction of 4-nitrodiphenylmethyl chloride with 4-nitrobenzaldehyde in the presence of alkali in aqueous dioxane at room temperature. 1,1-di-[4-nitrophenyl] ethylene oxide III was also prepared by reacting 4,4'-dinitrodiphenylmethyl chloride with paraformaldehyde under similar conditions. The structures of these new ethylene oxides I, II and III were confirmed by IR and PMR spectra, and their mass fragmentation patterns were discussed
