Pinacol Coupling Reactions

Radical Compatibility with Nonaqueous Electrolytes and Its Impact on an All‐Organic Redox Flow Battery

“…(3) in Scheme 2]. [16] This may explain why the TEA + results in slower radical fading than Li + in the same DME solvent. Specifically,while poorly coordinating to the oxygen atom in the FLC À ,the close proximity of the bulky TEA + cations may largely block as econd FLC À approaching the shielded reaction site,that is,the unpaired electron on the carbon atom.…”

Mischmetall and Zn–Cu Couple as Efficient Reagents for the Pinacol Coupling of Aldimines

“…1 They are biologically active and of therapeutic importance. 2,3 A modern approach to these compounds is based on the pinacol type coupling of carbonyl compounds 4,5 and their aza-analogues 6 and has been extensively studied during the last twenty years. 7 The synthesis of 1,2-diamines starts from imines and is mediated by a variety of metals and reduced metal compounds.…”

Absolute Configuration Determination of Azulenyl Diols Isolated From Asymmetric Pinacol Coupling

“…Among a large variety of chiral molecules, diols play an important role, since they serve as useful chiral auxiliaries for the synthesis of numerous pharmaceuticals and industrial products or as chiral ligands for transition metals forming efficient catalysts for various enantioselective reactions . Several synthetic methods for the preparation of these compounds have been extensively investigated, foremost being the McMurry pinacol reaction of carbonyl compounds . Therefore, during the past decades much effort has been made to develop diastereoselective and enantioselective variants of this reaction by using various additives .…”
