    3,8-Bis-(1-hydroxyethyl)deuteroporphyrin dimethyl ester(Ⅲ) was prepared from hemin(I) by the ways of HBr-H3CCOOH addition reaction,OH-nucleophilic substitution reaction and anhydrous hydrogen chloride catalyzed esterification. It was then oxidized by Jones reagent to form 3,8-bisacetyl deuteroporphyrin dimethyl ester(Ⅳ).

Nucleophilic substitution

  • abstract: In organic and inorganic chemistry, nucleophilic substitution is a fundamental class of reactions in which an electron nucleophile selectively bonds with or attacks the positive or partially positive charge of an atom or a group of atoms to replace a so called leaving group; the positive or partially positive atom is referred to as an electrophile. The whole molecular entity of which the electrophile and the leaving group are part is usually called the substrate.
