regioselective 1,3-dipolar cycloaddition. The present methodology capitalized on trichloroisocyanuric acid (TCCA) as a safe and ecological oxidant and chlorinating agent for the in-situ conversion of aldehydes to nitrileoxides in the presence of hydroxylamine hydrochloride, under ultrasound activation. These nitrileoxides could be engaged in 1,3-dipolar cycloadditionreactions with various alkene to
A lubricant oil composition which is excellent in wear resistance, high temperature detergency and base number retaining property, despite its low phosphorus content, low sulfur content and low sulfuric acid ash content, is provided at a low cost by compounding a sulfonamide compound having a specific structure in a base oil.
