Abstract
Provided are a fluorous-tag-introduced fluoroamine of a general formula (I), its production method, a method of fluorination of a substrate having functional group containing oxygen with the fluoroamine serving as a fluorinating agent, and a method of recovering a fluorous-tag-introduced amide after the fluorination. The fluoroamine and its production method, as well as the fluorination method with the fluoroamine and the method of recovery of a fluorous-tag-introduced amide are ecological and advantageous in industrial use, as the load for separating and collecting the product after the fluorination with the fluoroamine serving as a fluorinating agent is small. (In the formula, Ris an alkyl group or an aryl group having substituent(s) of Rf—(CH)—; Rf is a perfluoroalkyl group; m is from 0 to 2; Rand Reach are an alkyl group or an aryl group.)
