Abstract: Abstract 2,2,6,6-Tetramethyl-1-piperidinyl-N-oxyl (TEMPO) and its derivatives as stable radicals can participate in many reactions. During the process, TEMPO and its derivatives could act not only as the substrates to capture or initiate new radical intermediates… read more here.

Abstract: The 1,2,3-triazole and 1H-1,2,3-benzotriazole-substituted 6,7-dihydroindolizin-8(5H)-one derivatives were synthesized by the reaction of (E)-7-(arylmethylidene)-6,7-dihydroindolizin-8(5H)-ones with 1,2,3-triazole and 1H-1,2,3-benzotriazole in the presence of Selectfluor in moderate yield. The structures of all the products were characterized thoroughly by… read more here.
