  New Applications of Hetaryl Thioketones for the Synthesis of Hetaryl-Substituted Ethenes via ‘Two-Fold Extrusion Reaction’

  摘要：

  A series of aryl/hetaryl thioketones was applied for the reactions with aryl/hetaryldiazomethanes yielding, after elimination of N-2, the corresponding thiiranes. The relatively unstable dihetaryldiazomethanes were generated in situ from the corresponding hydrazones by oxidation with DMSO. The obtained thiiranes were converted into tetraaryl/hetaryl-substituted ethenes in good yields by desulfurization performed with tris(diethylamino)phosphine ((Et2N)(3)P).
