%0 Journal Article %T Hetero Diels-Alder adduct formation between nitrosobenzene and tetra-methyl purpurogallin and its retro-Diels-Alder reaction %A Gamenara Daniela %A D¨ªas Eduardo %A Tancred N¨¦stor %A Heinzen Horacio %J Journal of the Brazilian Chemical Society %D 2001 %I Sociedade Brasileira de Qu¨ªmica, SBQ %X An efficient synthesis of a Diels-Alder adduct between purpurogallin tetramethyl ether (TMPG) and nitrosobenzene (NOB) is reported. The thermal decomposition kinetics of the adduct, which follows a retro-Diels-Alder mechanism, was studied using 1H-NMR spectroscopy. %K Hetero Diels-Alder %K tetra-methyl purpurogallin %K nitrosobenzene %U http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-50532001000400008
