2-Propynyl chloroformate - Introduction
propargyl chloroformate(propargyl chloroformate) is an organic compound with the chemical formula CH3OC(O)OCC≡C. It is a colorless liquid with a pungent odor.
propargyl chloroformate are commonly used in esterification and carbonylation reactions in organic synthesis. It can be used as an esterification reagent to convert alcohols to esters. It can also be used in the synthesis of compounds containing carbonyl functional groups, such as aldehydes and ketones. In addition, propargyl chloroformate can also be used as intermediates for catalysts and reagents.
The preparation of propargyl chloroformate generally uses the reaction of chloroformate with propargyl alcohol. The reaction conditions can be base catalysis, inert solvents and low temperature.
For safety information, propargyl chloroformate is an irritating compound that may cause irritation to the skin, eyes, and respiratory tract. Wear protective gloves, goggles and respiratory protection equipment during operation. At the same time, it should be operated in a well-ventilated place to avoid inhaling its vapor. In addition, propargyl chloroformate pose a risk to the environment and should not be discharged directly into water or soil.
