1-[2-(2,6-Dichlorobenzyloxy)-2-(2-furyl)ethyl]-1H-1,2,4-triazole
In the molecule of the title compound, C15H13Cl2N3O2, the triazole ring is oriented at dihedral angles of 2.54 (13) and 44.43 (12)°, respectively with respect to the furan and dichlorobenzene rings. The dihedral angle between the dichlorobenzene and furan rings is 46.75 (12)°. In the crystal structure, intermolecular C—H⋯O hydrogen bonds link the molecules into centrosymmetric dimers and π–π contacts between dichlorobenzene rings [centroid–centroid distance = 3.583 (2) Å] may further stabilize the structure. Intermolecular C—H⋯π contacts between the triazole and furan rings also occur
Vitamin C and isovitamin C derived chemistry. 4. Synthesis of some novel furanone chirons
Neutral organic super electron donors made catalytic
Neutral organic super electron donors (SEDs) display impressive reducing power but, until now, it has not been possible to use them catalytically in radical chain reactions. This is because, following electron transfer, these donors form persistent radical cations that trap substrate-derived radicals. This paper unlocks a conceptually new approach to super electron donors that overcomes this issue, leading to the first catalytic neutral organic super electron donor
