The 14 and 70 eV electron ionization mass spectra of five sets (R1 = Me, Et, i‐Pr, t‐Bu and Ph) of seven 2‐aryl‐4‐R1‐substituted (Ar = C6H4X; X = p‐NO2, m‐Br, p‐Cl, H, p‐Me, p‐OMe and p‐NMe2) (1–5) and of seven 2‐aryl‐5‐phenyl‐substituted 1,3‐oxazolidines (6; for Ar, see above) were recorded to stud...
