| Abstract: | Two mild new chromium (VI) reagents derived from nicotinic acid and isonicotinic acid are described. Nicotinium dichromate (NDC) and isonicotinium dichromate (INDC) oxidize alcohols into carbonyl compounds, mercaptans into disulfides and hydroquinones into quinones. Oxidtion of polynuclear aromatic hydrocarbons is made. Pyridine assisted oxidations by means of these reagents are also described. |
