Abstract
Trois composés isomères de structures dihydro‐3a, 8a pyrazolo (3,4‐b) indole, hydrazone D'aryl indolyl cétone et triaryl‐1,3,4 pyrazole possèdent le měme spectre de masse; il est montré que celui‐ci résulte de la superposition des spectres des deux premiers composés en équilibre après ionisation. Les dihydro‐3a, 8a pyrazolo (4,3‐b) indoles résultant de la deuxième possibilité de cycloaddition, ont aussi les měmes fragmentations. Ces résultats rendent impossible le détermination par spectrométrie de masse, de la structure des produits formés lors de la réaction de cycloaddition.Keywords
