In this 1976 book, Professor de la Mare shows how those halogenations involving the whole gamut of unsaturated organic molecules can be linked through considering them as reactions involving the ...

A rapid intramolecular reaction with the carbonyl oxygen releases the strain in the cyclopropane ring, producing an electrophilic oxonium ion, which is in turn attacked in a Prins-type reaction by ...

SAM serves as the methyl donor for biological methylation, and this reaction proceeds readily based on the chemical reactivity of nucleophiles with its electrophilic sulfonium ion. In addition to ...
