Synthesen von zwei persubstituierten Monothiohydrochinonen und deren S‐Methylierung

Abstract: 1 -Hydroxy-4-mercapto-2.3.5.6-tetramethyl-benzol (Monothiodurohydrochinon, I) und l-Hydroxy-4-mercapto-2.3-dimethyl-naphthalin (Monothio-2.3-dimethyl-l.4-naphthohydrochinon, 11) wurden uber die entsprechenden Rhodanverbindungen synthetisiert. Mit einem Mol-Wquiv. Methyljodid wurden sie nur am Schwefel methyliert. Die Thioather lielen sich mit verschiedenen Reagentien unter S-Eliminierung zu den Chinonen oxydieren. Monothiohydrochinonesind vor iiber 50 Jahren in den Laboratorien vonTH. ZINCKE*) 1) Aus der Disse… Show more
