Visible-light-induced metal and reagent-free oxidative coupling of: Sp 2 C-H bonds with organo-dichalcogenides: Synthesis of 3-organochalcogenyl indoles

Here, a unique visible-light-induced method for the organochalcogenation of the sp2 C-H bonds of indoles and aniline has been presented using diaryl dichalcogenides (S, Se, and Te) and oxygen as an oxidant avoiding a photocatalyst, base, catalyst, and reagent in acetone at room temperature. This benign protocol allows one to access a wide range of 3-arylselenylindoles, 3-arylthioindoles and even 3-aryltelluroindoles with good to excellent yields. Various functionalities namely, methoxy, and halo either on indoles or aryl dichalcogenides showed amenability to the developed reaction. Furthermore, thiocyanation of the sp2 C-H bonds of indoles has been accomplished by this visible light induced method. A mechanistic understanding by UV-visible, EPR spectroscopy, and cyclic voltammetry suggests that light induces electron transfer from the electron rich arene to oxygen providing an arene radical cation and a superoxide radical anion. Subsequently, reaction of the radical cation with aryl dichalcogenides provides a diaryl chalcogenyl cation which upon removal of protons gave unsymmetrical 3-indolyl aryl chalcogenides.

FLUOROALKYLATING AGENT

Problem to be Solved It is intended to provide an industrially preferable fluoroalkylating agent and use thereof. Solution The present invention provides a fluoroalkylating agent represented by the general formula (1) wherein R1 is a C1 to C8 fluoroalkyl group; R2 and R3 are each independently a C1 to C12 alkyl group or the like; Y1 to Y4 are each independently a hydrogen atom, a halogen atom, or the like; and X? is a monovalent anion. A compound of the general formula (3): R4—S—R1 having an introduced C1 to C8 fluoroalkyl group is easily obtained by reacting a compound of the general formula (2): R4—S—Z wherein R4 is a hydrocarbon group or the like; and Z is a leaving group, with the compound of the general formula (1).
