C. %A Silva Jr. Luiz F. %J Journal of the Brazilian Chemical Society %D 2001 %I Sociedade Brasileira de Qu¨Şmica, SBQ %X The reaction of some cis-2-decalones with TTN in CH2Cl2 at room temperature was investigated. The ring contraction reactions occurred in good yields, however the regio- and diastereoselectivity were low. The effect of the alkyl groups in the regiochemistry of the reaction depends on their position at the decalone ring system. %K thallium trinitrate %K oxidation %K hydrindanes %K ring contraction %K decalones %U http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-50532001000400018
