26 February, 2015, India, USA NEWS CORPNoor Ud Din Zargar* and K.Z. Khan receive World Chemical Science Award-2015. The research findings were published on world's prestigious most read journal: The Journal of Chemical Science. Dimethylsulphoxide acetic-anhydride reagent converts 1,3-indandione to the ylide (2) and a dimer 1H,1/H- 2,2/-biindene 1,1/-3,3/(2H,2/H)-tetrone(3) at room temperature but brings about Wittig type synthesis of 2-dimethyl sulphonium-2/,3-biindene-1,1/,3/-trione(4)by alternate workup process under similar conditions. However,at water bath temperature the reaction affords an oxidative cyclisation product 2-methyl-1,2/-biindene 1/,3,3/(2H)trione (5) along with (2) and (4). Authors are thankful to Department of Chemistry, University of Kashmir for providing all the research facilities. Zargar N.D. is also thankful to supervisor Prof. K.Z. Khan for encouragement. Authors are highly grateful to RSIC Chandigarh Punjab University, India for recording spectra of the compounds.
