Syntheses with Alkenediazonium Salts, V. Synthesis and Structure of 1,3,4-Oxadiazoles, 6H-1,3,4-Oxadiazines, and 5,6-Dihydro-4H-1,3,4-oxadiazinesDepending on the substituents R1 and R2 the reaction of alkenediazonium salts 1 with carboxylic hydrazides 2 leads to 1,3,4-oxadiazoles 6, 6H-1,3,4-oxadiazines 7, and 5,6-dihydro-4H-1,3,4-oxadiazines 8, respectively. The structures of 6b, 7Be, and 8b were established by X-ray analysis.
Notes:
Die Umsetzung von Alkendiazoniumsalzen 1 mit Carbonsäurehydraziden 2 führt in Abhängigkeit von den Substituenten R1 und R2 zu 1,3,4-Oxadiazolen 6, 6H-1,3,4-Oxadiazinen 7 bzw. zu 5,6-Dihydro-4H-1,3,4-oxadiazinen 8. Zur Sicherung der Konstitution von 6b, 7Be und 8b wurden Röntgenstrukturanalysen durchgeführt.
