Abstract
έθοδος παρασκευής 4,4'-διοξυ-διαφαινυλο-(2-πυριδυλο)-μεθανίου, χαρακτηριζομένη εκ του σταδίου της συμπυκνώσεως 2-πυριδιναλδεϋδης ή παραγώγου τινος ταύτης δυναμένου να αντιδράση, παρουσία μέσου τινός συμπυκνώσεως, μετά φαινόλης του τύπου: Τύπος Ι - εις τον οποίον τα R1 και R2. όμοια ή διάφορα, παριστούν άτομον αλογόνον ή υδρογόνου και τουλάχιστον εις εκ των υποκαταστατών R1 ή R2 είναι άτομον αλογόνου - οπότε σχηματίζεται ένωσις του γενικού τύπου: Τύπος ΙΙ - εις τον οποίον τα R1 και R2 εις εκάστην βενζολικόν πυρήνα, παριστούν ότι προηγουμένως καθωρίσθη - και υπό του σταδίου της αφαλογονώσεως της ούτω ληφθείσης ενώσεως (ΙΙ), τη βοηθεία κράματοςΝικελίου κατά RANEY, παρουσία καυστικών αλκαλίων. Process for the preparation of 4,4'-dioxy-diphenyl- (2-pyridyl) -methane, characterized by the step of condensing 2-pyridinaldehyde or a derivative thereof which can be reacted in the presence of a concentrate, then phenol of the formula: Type I in which R1 and R2. similar or different, represent a halogen or hydrogen atom and at least one of the substituents R1 or R2 is a halogen atom - thus forming a compound of general formula: Type II in which R1 and R2 in each benzene nucleus are shown to have previously defined - and under the decolonization step of the compound (II) thus obtained, the RANEY nickel alloy aid in the presence of caustic alkalis.
