Abstract
The present invention relates to a method for synthesizing a 2-benzylidene tetrahydrothiophene derivative, which comprises the step of reacting a (cyclopropylethynyl) aromatic cyclic compound of Formula (I) with a sulfur source in an organic solvent as a reaction medium in air atmosphere at 100-200° C. to obtain a 2-benzylidene tetrahydrothiophene derivative of Formula (III). The reaction route is as follows:
