Synthesis of Unusual Trimers in 1,3-Indandione

N. D. Zargar, K. Z. Khan

Abstract


Dimethyl Sulphoxide-acetic anhydride reagent converts 1,3-indandione to the ylide (2) and a much awaited dimer (3) at room temperature. However , when 1,3-indandione was interacted with pre- heated  DMSO-acetic anhydride  at  waterbath temperature it affords an unusual trimer (4) and a novel compound (5), methine-tris-1,3-indandione  along with the ylide (2)

Key words: DMSO, Acetic anhydride, Indandione,Ylide Trimer.
