Synthesis of Unusual Trimers in 1,3-Indandione
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.
