Selective oxidation of benzyl alcohol by two phase electrolysis using nitrate as mediator

Redox-mediated oxidation of alcohols using Cl− /OCl− redox couple in biphasic media

“…The equations are given under Scheme as follows. An identical mechanism has also been proposed earlier …”

“…Oxidation of benzyl alcohol to benzaldehyde using two‐phase electrolysis method has been studied with carbon anode and stainless steel cathode. High yield of benzaldehyde (95%) with a high CE (95%) was achieved . The use of Br − /OBr − and NO 3 − /NO 3 .…”

Synthetic Organic Electrochemical Methods Since 2000: On the Verge of a Renaissance

“…208,209 Halides and hypohalite anions could also serve as mediators in the anodic oxidation of alcohols (Figure 12I–K). For example, electrochemical methods for the oxidative cleavage of diols have been reported wherein sodium periodate is anodically generated in a biphasic system (Figure 12I); 210 unmediated diol cleavage has also been described.…”

An Expanded SET Model Associated with the Functional Hindrance Dominates the Amide-Directed Distal sp3 C–H Functionalization

“…Thermally or photochemically generated radicals inherently exhibit short-lived, high-energetic, and highly reactive characteristics and thus serve as an important class of versatile and highly active species in organic synthesis. − Recent advances in radical chemistry have stimulated considerable interest in exploring new synthetic platforms to enable the challenging radical transformations associated with the elusive rearrangement reactions. − These efforts call for a large-scale renaissance of radical-based methodologies that first emerged with the electrochemical decarboxylation reaction in the 1840s and then underwent a multicentennial period of exploration, eventually leading to an unprecedented prosperity in multiple directions of radical chemistry at the beginning of the 21st century. − , The experimental findings on the radical-mediated approaches show that by employing different additives the radical species can be variously produced in electrolytic, − photolytic, − oxidative − or reductive homolytic, − and transition-metal-based catalytic − or metal-free − systems. Although the used additive is roughly classified as an initiator − or a catalyst − ,− …”
