Synthesis of 2,3,5-triaryl-4-trifluoromethyl thiophenes

Triaryl-β-trifluoromethyl thiophenes are synthesized from 1,3-dithiolium-4-olates and various substituted 1-aryl-3,3,3-trifluoro-1-propynes. The spectroscopic characteristics of the products and the regioselectivity of the reaction are discussed.

Thiophenes useful in control of acarids

Substituted thiophenes of the following formula, some of which are new compounds, are useful in controlling certain pests, particularly mites: STR1 wherein A, Y and Z are various substituents such as phenyl and substituted phenyl.
