| Abstract: | On photolysis of the titled compound around its λmax (360 nm), it rearranges to 6-chloro-3-hydroxy-3-(2'-thienyl)-1,2-indandione as analysed by IR, NMR and by coupling with o-phenylenediamine. Quantitative analysis of the photolysed mixture by spectral measurements also confirms it. Quantum yield of the product is low (~0.05), which is not affected by the polarity of the solvent. |
