5-Phenyl-2-phenylimino-4-oxazolidinone exists in DMSO-D6 in the form of a mixture of the E and Z isomers of the imino tautomer, but it crystallizes in the amino form.Parallelism between the basicity and nucleophilicity of the reaction centers of this mesomeric anion is observed when the alternative isomers (and the tautomers corresponding to them) differ significantly in stability.If this condition is not fulfilled, these parameters do not coincide, as is illustrated in the example of its methylation reaction.
