tolüülsulfonaatmetüül

tolüülsulfonaatmetüül is a chemical compound also known by its systematic name methyl p-toluenesulfonate. It is an ester formed from p-toluenesulfonic acid and methanol. Its chemical formula is C8H10O3S. This colorless liquid or solid, depending on purity and temperature, is characterized by its relatively high boiling point and solubility in many organic solvents.

In organic chemistry, tolylüülsulfonaatmetüül serves as a methylating agent. The tosylate group (p-toluenesulfonate) is an excellent leaving group, which facilitates the transfer of the methyl group to nucleophiles. This property makes it useful in various synthetic transformations for introducing a methyl group onto oxygen, nitrogen, or carbon atoms. It can be employed in the synthesis of ethers, esters, and amines.

The preparation of tolylüülsulfonaatmetüül typically involves the reaction of p-toluenesulfonyl chloride with methanol in the presence of a base, or the reaction of p-toluenesulfonic acid with a methylating agent like dimethyl sulfate. Due to its reactivity, it should be handled with appropriate safety precautions in a laboratory setting.
