“…However, the literature has been mainly concerned with end uses for this class of compound, and details of synthesis and characterization are scarce. There are many references to the synthesis of monosulfonyl azides,18–29 and some texts contain information about the synthesis of a limited number of disulfonyl azides,4, 6, 18, 30–33 although characterization has been only by melting point and elemental analysis. The aim of this article is to give an account of the syntheses of 1,6‐hexanedisulfonyl azide, 1,10‐decanedisulfonyl azide, 1,3‐benzenedisulfonyl azide, 1,5‐naphthalenedisulfonyl azide, 2,6‐naphthalenedisulfonyl azide, and 4,4′‐biphenyldisulfonyl azide from readily available starting materials and to give a full characterization of these compounds.…”

ROKURO FUJITA und MINORU IMOTO (Eingegangen am 17. Oktober 1967) ZUSAMMENFASSUNG:Die Zersetzung von p-substituierten Arylsulfonylaziden sowie die durch diese Azide initiierte Polymerisation wurden in Naphthalinlosung im Temperaturbereich von 110 bis 135OC untersucht. Die Zersetzungsgeschwindigkeit der Azide ist in bezug auf die Ausgangskonzentration von der ersten Ordnung. Die Bruttoaktivierungsenergie der Zersetzung des Benzolsulfonylazids wurde zu 36,4 kcal/mol abgeschatzt. Die modifizierte HmMEmsche Gleichung gilt sowohl fiir die Zersetzung als auch fur die Polymerisation. Die Vinylpolymerisation durch die unter UV-Bestrahlung zersetzten Azide gelang bei 30 OC. SUMMARY:The decomposition of p-substituted arylsulfonyl azides and the polymerization initiated by these azides was studied in naphthalene in the temperature range from 110 to 135OC. The rate of decomposition was found to be first order on the initial concentration of the azides. The overall activation energy of the decomposition of benzenesulfonyl azide was estimated as 36.4 kcal/mole. Modified HAMMETT'S equation is applicable both for the decomposition and for the polymerization. Vinyl polymerization by the azides was further carried out at 3OoC under UV-irradiation.

Asahara and coworkers have reported that methyl methacrylate') and polymerize in the presence of an anionic surfactant without an initiator. They suggested that an interaction between the vinyl monomers and the micelle of the surfactant participates in the polymerization.We found that styrene polymerizes in an aqueous system on irradiation with a tungsten lamp in the presence of N-laurylpyridinium azide (1). A comparable polymerization is unknown and the reaction mechanism is still obscure. In this communication some observations will be described. Experiment a1 Part N-Laurylpyridinium azide (1):The preparation and analysis of 1 were performed according to the procedures reported previously4': 1 was prepared from N-laurylpyridinium chloride (LPC) and sodium azide by ion-exchange reaction (8 h) in purified tetrahydrofuran (THF) in the dark. The ion-exchange ratio was 98%. The chemical grade sodium azide was extracted with purified THF in a Soxhlet extractor before the ion-exchange reaction to remove THF soluble impurities, otherwise the obtained 1 became sometimes uneffective.Cetyltrimeth~~lammonium chloride (CTAC): Chemical grade product was recrystallized from THF. Cetyltrimethylammonium azide (CTAA): A similar ion-exchange procedure gave CTAA from CTAC;Vinyl monomers: All vinyl monomers were purified by usual methods.the ion-exchange ratio was 97 %.
