Abstract

Dimethyl sulphoxide reagent brings about N-methyl thiomethylation and N-hydroxy methylation in phthalimide at elevated temperature. It also converts 5,5-disubstituted barbituric acid to its N-methyl thiomethyl and N,N^/-methyl thiomethyl derivatives at reflux temperature. A convenient and efficient procedure for the synthesis of poly(methylene-bis)-1,3-indandione derivative (2) was developed by one-pot reaction of 1,3-indandione (1) when refluxed with DMSO at 180°C . This provides an alternate method of mechanistic interest for the synthesis of tetrad (2) with excellent yield. The condensation product (2) can act as a basic unit for the synthesis of a polymer.
