Azzena, Ugo; Demartis, Salvatore; Melloni, Giovanni published the artcile< Electron-Transfer-Induced Reductive Cleavage of Phthalans: Reactivity and Synthetic Applications>, Quality Control of 112-63-0, the main research area is electron transfer phthalan reduction; isobenzofuran phthalan reductive electron transfer cleavage; isocoumarin preparation; coumarin preparation; benzopyran preparation; isobenzopyran preparation; naphthalenemethanol preparation; regiochem phthalan reductive electron transfer cleavage.
The behavior of phthalan (1,3-dihydroisobenzofuran) was investigated under conditions of electron transfer from alkali metals in aprotic solvents. Reaction with lithium in the presence of a catalytic amount of naphthalene in THF led to the reductive cleavage of an arylmethyl carbon-oxygen bond, with formation of a stable dilithium compound Trapping of this intermediate with several electrophiles (alkyl halides, carbonyl derivatives, CO2) was successful. The extension of this procedure to several substituted phthalans was investigated, and the regiochem. as well as the synthetic usefulness of these reactions are discussed.
Journal of Organic Chemistry published new progress about Electron transfer. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Quality Control of 112-63-0.
