Endeavor to discover biorational natural products-based fungicides, two series (26) of novel 1-sulfonyloxy/acyloxydihydroeugenol derivatives (3a–p and 5a–j) were prepared and assessed for their fungicidal activity against P. capsici Leonian, in vitro. Res

The kinetics of the methanolysis of benzoyl bromide and eight para- or meta-substituted derivatives in acetonitrile at 25.0 deg C can be analysed in terms of the simultaneous operation of overall second- and third-order processes.In turn, each of these processes can be analysed in terms of the simultaneous operation of two reaction channels, which are proposed to involve a carbonyl addition-elimination mechanism (favoured for electron-withdrawing substituents) and a process (SN2-SN1) proceeding through a loose SN2-type transition state.For the p-methoxybenzoyl bromide substrate, a third reaction channel is observed, but only for the overall second-order process (first-order in methanol), and this is tentatively described as involving electrophilic assistance by a methanol molecule to an ionization (SN1) pathway.
