A catalyst- and additive-free sunlight-induced strategy for autoxidation of a wide range of aldehydes RCHO (R = Bu, cyclohexyl, Ph, pyridin-3-yl, etc.) to carboxylic acids RC(O)OH is described for the first time. In this oxidation system, air serves as the source of oxygen and sunlight as the light source, and the system includes the advantages of green, highly atom-efficient, and low-cost synthesis. This method was easily applied even at gram scale. The reaction proceeds smoothly even at lower temperature and in natural light. The experimental process involved the reaction of 3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0Computed Properties of C9H8O4)
3-(Methoxycarbonyl)benzoic acid(cas: 1877-71-0) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones.Computed Properties of C9H8O4
