摘要:The present invention provides: a substrate for achieving the highly efficient synthesis of an aryl compound containing a tritylsulfanyl group; a method for producing a compound containing an SF 5 group using the substrate; and others. The present invention is a method for producing an aryl compound containing a tritylsulfanyl group, the method comprising thiotritylating a halogenated aryl compound represented by general formula (1) [wherein A 1 represents an aryl group that may have a substituent or a heteroaryl group that may have a substituent; and X represents a halogen atom] using [(triphenylmethyl)sulfanyl]potassium or [(triphenylmethyl)sulfanyl]sodium to produce an aryl compound containing a tritylsulfanyl group, the aryl compound being represented by general formula (2) [wherein A 1 is the same as A 1 in general formula (1); and Ph represents a phenyl group].
