RESUMO
Irradiation of 2-phenyl-5-[2-thienyi]-tetrazole 1 with acrylate derivatives 2A-E [molar ratio 1:1] in anhydrous benzene gave the corresponding title compounds 1-phenyl-3-[2-thienyl]-pyrazoline derivatives 4A-E as end products. The mechanism and the regiochemistry of the studied reactions are discussed
