A production method in which a mercaptophenol compound is obtained using an industrially preferred sulfur atom introduction reaction, and intermediate compounds of the mercaptophenol compound are provided. A method for producing a mercaptophenol compound in which a phenyl carbamate compound is produced using a phenol compound as a raw material, and then a sulfur atom is regioselectively introduced by a reaction with sulfur monochloride, and a phenyl mercaptocarbamate compound is produced as an intermediate.

ortho-olefinated phenol carbamate, including a ruthenium(II)-catalyzed oxidative olefination of phenol carbamate with acrylates and a rhodium(III)-catalyzedalkynehydroarylation of phenol carbamate with internal alkynes through direct C–H activation, are reported. Both reactions afford substituted alkenes in a highly regio- and stereoselective manner.

reactive C-H bonds are present on the O-phenylcarbamate, selective diarylation can be achieved via quadruple C-Hbond functionalization. This work represents a rare example of using O-carbamates as directing groups for catalytic C-Hbondactivation. Additionally, a palladacycle obtained from an O-phenylcarbamate was prepared and fully characterized. This trifluoroacetate-bridged bimetallic Pd complex
