Die Konstitution des Naphthalins und seiner Derivate

Abstract: Die Frage nach der Konstitution des Naphthalins, die lange Zeit zugunsten der Erlenmeyer-Graebeschen symmetrischen Formel I entschieden zu sein schien, ist in den letzten Jahren unter neuen Gesichtspunkten wiederholt erortert worden, ohne da13 jedoch eine Ubereinstimmung der verschiedenen Ansichten erzielt werden konnte. v. Auwers2) hat aus seinen spektrochemischen Untersuchungen den SchluB gezogen, dal3 den Beobachtungen am besten die -wohl zuerst von H. E r d m a n n s ) aufgestellte -asymmetrische Formel I1… Show more
