The invention discloses a method for substituting a compound by fluoroalkane, which comprises the following steps: the compound containing carbon-carbon double bonds and halogenated fluoroalkane are taken as raw materials, a metal simple substance is taken as a reducing agent, a substance containing active protons is taken as a hydrogen source, and an addition reaction is carried out to prepare the compound substituted by hydrogen and fluoroalkyl simultaneously, so that the fluoroalkane substituted compound is obtained. According to the invention, a metal simple substance is used as a reducing agent for the first time, a compound containing active hydrogen is used as a hydrogen source, a hydrogen atom and a fluoroalkyl are respectively introduced into two ends of olefin, and only one-step reaction is needed, the reaction process conditions are mild, the reaction raw materials are cheap and easy to obtain, the cost is low, and all reaction reagents are green and environment-friendly; the substrate applicability of the reaction is strong, the reaction can be participated in as long as carbon-carbon double bonds exist in the structure, the influence of the types of substituents on double-bond carbon atoms is avoided, and the yield of the product is good. |
