Electro‐oxidative Methylation of 2‐Isocyanobiaryls Using N,N‐dimethylformamide (DMF) as Carbon Source: Synthesis of 6‐Methylphenanthridines

Chemistry - An Asian Journal, Год журнала: 2024, Номер 19(9)

Опубликована: Март 16, 2024

A benign electrochemical method to access 6-methylphenanthridines from 2-isocyanobiaryls using N,N-dimethylformamide (DMF) as a methyl source is reported. The protocol operates at ambient temperature without the need for harmful methylating reagents. Mechanistic studies suggested that DMF delivered methylene synthon, followed by reduction cathode and tautomerization. offers environmental benefits avoiding metal-based reagents harsh conditions.
