Diazomethane adds to one of the two faces of the sterically hindered thiofenchone furnishing the title compound wich extrudes N2 at 46 deg C whith t_1/2=22 min; the thiofenchone S-methylide is intercepted by dipolarophiles and acts as a base in reactions with methanol, thiophenol and acetic acid, in the latter case accompanied by skeletal rearrangement.
