“…For the imidate XXI, when R = CH3-, a stabilizing effect was noted as compared with R = C6H6-or C1CH2CH2-; RC(=NH2Cl)OR' XXI further, when R' = Ar, a greatly enhanced stability ensued as prolonged heating at 70°C. gave little decomposition (226). When, for XXI, R = CHC12-, CCI3-, CBr3-, N02CH2-, or CC12(N02)-, the instability of the imidate salts was such that the corresponding substituted acetamides were isolated instead of the methyl imidate salts (306).…”
