The photochem. codimerization of benzofuran with 2-substituted benzofurans has been examined. Irradiation of benzofuran with 2-(3-pyridyl)benzofuran or 2-phenylbenzofuran gave the head-to-tail syn- (I, R = 3-pyridyl or Ph) and anti-cyclobutane codimers (I, α-H) as main products. Benzofuran with Me benzofuran-2-carboxylate on irradiation gave the head-to-head syn codimer II in addition to one homodimer of Me benzofuran-2-carboxylate and two carbonyl compounds III and IV. The former proceeds via the excited singlet of benzofuran and the latter involves the excited singlet of Me benzofuran-2-carboxylate. In the experiment, the researchers used many compounds, for example, Methyl benzofuran-2-carboxylate (cas: 1646-27-1Recommanded Product: Methyl benzofuran-2-carboxylate).
Methyl benzofuran-2-carboxylate (cas: 1646-27-1) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.Recommanded Product: Methyl benzofuran-2-carboxylate
