Die Synthese von Benzolderivaten aus Kohlenoxyd und Kalium

Abstract: 1833 beschreiben werde, bestiitigen im vollen Maasse die aus der Verbrennungswarme des Benzols abgeleitete Constitution desselben, d. h. die Gegenwart von 9 einfachen Bindungen im Molekiil. Aehnliche Untersuchungen iiber die Verbrennungswiirme des Thiaphens, iiber welche ich auch in dem vierten Bande berichten werde, fiihren zu dem Schluss, dass Thiophen k e i n e d o p p e l t e n Bind-ungen enthalt, sondern d a s s d i e vier K o h l e n s t o f f a t o m e des T h i o p h e n s durch fiinf einfache Bindunge… Show more

“…31,32 The hexa iodo-, bromo-, chloro-, hexamethyl-, and hexahydroxy-benzenes (and hexahydroxylates) have also been known since the 19th century. 33−40 Hexafluorobenzene was only first synthesized in 1956, 41 but now, it is widely used as a valuable solvent and standard in 19 F NMR. Hexaaminobenzene was first synthesized in 1929, and its crystalline state was already characterized in 1931.…”

“…This was followed by an argument from Brodie, that the mixture contains the hexapotassium salt of hexahydroxybenzene C 6 (OK) 6 [2a,b] . Since investigations from Nietzki and Benckiser, the compound of the formula [KCO] n is considered as K 6 O 6 C 6 without any information about the formed amounts, [3a] supported by a paper by Kröger and co‐workers [3b] . Weygandt et al.…”

“…Fox and coworkers [16] have synthesized two closely related series of porphyrin discogens. Esters of porphyrin octa-acetic acid were prepared according to Scheme 43, porphyrin octa-acetic acid being prepared following the procedure of Franck [160].…”
