Substitution reactions under NH3 chemical ionization conditions incis-/trans-1,2-dihydroxybenzosuberans
摘要:
AbstractThe nucleophilic substitution reaction under NH3 chemical ionization (CI) conditions in cis‐ and trans‐1,2‐dihydroxybenzosuberans (1–4) has been studied with the help of ND3 CI and metastable data. The results indicate that in the parent diols 1 (cis) and 2 (trans), the substitution ion [MsH]+, is produced mainly by the loss of H2O from the [MNH4]+ ion (SNi reaction) while in their 7‐methoxy derivatives 3 and 4, the ion‐molecule reaction between [MOH]+ and NH3 seems to be the major pathway for the formation of [MsH]+. The substitution ion from 1 and 2 and the [MH]+ ion from trans‐1‐amino‐2‐hydroxybenzosuberan give similar collision‐induced dissociation mass‐analysed ion kinetic energy spectra. Interestingly, their diacetates do not undergo the substitution reaction.
