The electrochem. reduction of anthracenes in the presence of esters and chlorotrimethylsilane in LiClO4/THF in the undivided cell equipped with magnesium electrodes affords the corresponding cyclized products at low to moderate yields. Herein, the chem. structure of the product is determined by X-ray anal., as well as 1H NMR, 13C NMR, and HRMS. The in situ generation of magnesium anthracenes is indicated. The scope and limitations of the current reactions using anthracene and its derivatives with various esters are investigated. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Reference of 106-73-0).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
