Abstract
έθοδος δια την παρασκευήν μιας νέας ενώσεως θειαπυράνης, διακρινομένη εκ τούτου, ότι εν ακετυλίδιοντων μετάλλων των αλκαλίων φέρομεν εις αντίδρασιν με τετραϋδρο-1,4-θειαπυρόνην και υποβάλλομεν εις υδρόλυσιν το σχηματισθέν σύμπλοκον μετάλλου προς σηματισμόν της 4-αιθινυλοτετραϋδροθειαπυρανο-4-όλης.
