Zur Kenntnis des Kohlenstoffringes. 55. Mitteilung. Über einige 2,6‐(Oxa‐polymethylen)‐benzochinone und ihre Reduktionspotentiale

Abstract: Volumen XXXIII, Fasciculus VI (1950) -No. 244. 1937 244. Zur Kenntnis des Kohlenstoffringes. Uber einige 2,6-( Oxa-polymethy1en)-benzochinone und ihre Reduktionspotentiale von V. Prelog, M. Fausy El-Neweihy u n d 0. Hafliger. (4. IX. 50.) 55. Mitteilungl).Die Reduktionspotentiale der 2,6-Polymethylen-benzochinone mit weniger als 13 Ringgliodern im grossen Ring sind stark von der Ringgrosse abhangig. Mit der Verringerung der Ringgliederzahl werden die Chinone gegenuber den Hydrochinonen stabilisiert, die Redukt… Show more

“…Values have been obtained for a number of polymethylene quiñones having the following structures and compared xvith that of 2,6-diethylbenzoquinone in order to determine whether or not the rings were strain-free. Oxidation of the corresponding hydroquinones at the same point established the reversibility of the system (146,148,149).…”

“…volves oxygen and nitrogen. The case of oxygen is represented by only a single example (92). A far more extensive series of N-substituted cyclic amino acyloins has been prepared which includes both variation of substituent and ring size (69,70,(72)(73)(74)(75).…”
