But-3-enylzinc bromide, 0.50 M in THF - Introduction
But-3-enylzinc bromide is an organozinc compound with the chemical formula C4H7BrZn. It is a colorless liquid, soluble in organic solvents such as ether and carbon disulfide.
But-3-enylzinc bromide has a wide range of applications, mainly for organic synthesis as an important reagent. It can be used as an electronic reagent, a nucleophile or a group transfer reagent in organic synthesis. It can react with other organic substances, such as ketones and aldehydes to form alcohols; and carboxylic acids to form esters. It may also participate in carbonylation reactions, reduction reactions, rearrangement reactions, and the like of organic olefins.
But-3-enylzinc bromide are typically prepared by reacting zinc bromide and 3-butenyl bromide. During the preparation process, attention should be paid to the use of clean glass instruments, anhydrous solvents and desiccants to avoid the interference of moisture and oxygen on the reaction.
When using But-3-enylzinc bromide, you need to pay attention to its safety. It is a flammable liquid and should be avoided from contact with open flames or high temperatures. Wear appropriate personal protective equipment such as chemical protective gloves and goggles during operation. In addition, it should be stored in a dry and well-ventilated place, and stored separately from oxidants, acids and other substances to avoid accidents.
