Abstract

εφεύρεσις αφορά: 1. Εν τη ιδιότητι των εν νέων βιομηχανικών προϊόντων, τα διφαινυλοσουλφίδια του γενικού τύπου: [*] εις τον οποίο το Χ παριστά άτομον αλογόνου, το δε Υ νιτρο ή αμινομάδα, ενώ ο εις ήκαι οι δύο βενζολικοί πυρήνες δύνανται ενδεχομένως να φέρουν επί πλέον και άλλους υποκαταστάτας. 2.Μέθοδον παρασκευής των ενώσεων της παραγράφου Ι, εις τον τύπον των οποίων το Υ παριστά νιτροομάδα, ήτις περιλαμβάνει την επίδρασιν ενός ο-αλογονο-νιτροβενζολίου επί μιας ο-αλογονοθειοφαινόλης, του ενός ή και των δύο αντιδρώντων σωμάτων δυναμένων να φέρουν υποκαταστάτας εις τον πυρήν αναλόγως της φύσεως του διφαινυλοσουλφιδίου, το οποίον επιθυμεί τις να λάβη. 3. Μέθοδος παρασκευής των ενώσεων της αξιώσεων 1, εις τον τύπον των οποίων το Υ παριστά νιτροομάδα, ήτις περιλαμβάνει την διαζώτωσιν ενός αμινο-2-νιτρο-2' διφαινολοσουλφιδίου και την μετατροπήν του ληφθέντος διαζωνιακού άλατος εις αλογονο-2-νιτρο-2 διφαινυλοσουλφίδιον, δια μιας των γνωστών μεθόδων μετατροπής αρωματικού διαζωνιακούάλατοςεις τ' αντίστοιχον αρωματικόν αλογονίδιον. 4. Μέθοδος παρασκευής των ενώσεων, της αξιώσεως 1, εις τον τύπον των οποίων το Υ παριστά αμινομάδα, ήτις περιλαμβάνει την αναγωγήν των αντιστοίχων νιτροενώσεων, των λαμβανομένων κατά τας αξιώσεις 2 και 3, δια γνωστών μεθόδων αναγωγής νιτροομάδος προς αμινομάδα. invention relates to: 1. As new industrial products, diphenylsulfides of general type: [*] in which X represents a halogen atom, and Y represents a nitro or amino group, while the one or both benzene nuclei may additionally have other substituents. A process for preparing the compounds of paragraph I, in the formula of which Y represents a nitro group, comprising the effect of an o-halo-nitrobenzene on an o-halogenothiophenol, one or both of the reactants capable of having a substituent on the nucleus depending on the nature of the diphenylsulfide he wishes to receive. A process for the preparation of the compounds of claims 1, wherein the Y represents a nitro group, comprising the diazotization of an amino-2-nitro-2 'diphenolsulfide and the conversion of the obtained diazonium salt to halogen-2-nitron-2-nitron-halide. , by one of the known methods of converting aromatic diazonium salts to the corresponding aromatic halide. A process for the preparation of the compounds of claim 1, wherein Y represents an amino group, comprising reducing the corresponding nitro compounds, obtained according to claims 2 and 3, by known methods of reducing a nitro group to an amino group.
