Dimethyl formamide (L) MF) has been employed extensively in synthetic'organie chemistry as a useful reagent (2). In formylation reactions it is often used in conjunction with thionyl chloride (3) or phosphorus oxychloride (4). In a few reactions, the formylation of aromatic amins has been achieved with DMF under basic condition (5). Zollcwicz (6) cyclized o- aminonilrilcs with DMF under acid-catalyzed conditions and an intermediate forrnyl ...
