Hmc. Ferraz et al., The reaction of 1-tetralones with thallium trinitrate supported on clay: Ring contraction vs alpha-oxidation, J BRAZ CHEM, 12(5), 2001, pp. 680-684
The reaction of a series of 1-tetralones with thallium trinitrate supported
on Montmorillonite K-10 clay led to products of ring contraction (methyl i
ndan-1-carboxylates) and/or alpha -oxidation (2-methoxy-1-tetralones), in v
ariable yields.
