개요
Cyclopropyl bromide is also named as Bromocyclopropane. It is used in organic synthesis, for instance, for the formation of a Grignard Reagent, cyclopropyllithium. It is also used as an intermediate in the manufacture of pharmaceutical and agrochemical products.화학적 성질
Light yellow to clear colourless liquid, boiling point 67-69°C, refractive index (nD20) 1.4605, density (d420) 1.5120, flash point -6°C.용도
Bromocyclopropane is primarily used an intermediate in the manufacture of pharmaceutical and agrochemical products. It is also used in the production of cyclopropyl boric acid. It is used as an intermediate in organic synethesis.제조 방법
Bromocyclopropane has been prepared by the Hunsdiecker reaction by adding silver cyclopropanecarboxylate to bromine in dichlorodifluoromethane at ?29° (53% yield) or in tetrachloroethane at ?20° to ?25° (15–20% yield). Decomposition of the peroxide of cyclopropanecarboxylic acid in the presence of carbon tetrabromide gave bromocyclopropane in 43% yield. An attempt to prepare the bromide via the von Braun reaction was unsuccessful. Ten percent yields are reported for the photobromination of cyclopropane and the photochemical rearrangement of allyl bromide. Treatment of 1,1,3-tribromopropane with methyllithium prepared from methyl bromide furnishes a 60–65% yield of bromocyclopropane.주요 응용
Bromocyclopropane have anti-angiogenic effects that inhibits the growth of new blood vessels by interfering with the production of prostaglandins and nitric oxide, which are important for the formation of new blood vessels. Bromocyclopropane binds to cyclopropyl and hydrochloric acid, forming a hydrogen bond. It also forms a hydrogen bond with fatty acids and an a-type hydroxyl group.참고 문헌
