Geminal Vinyl Diazides, VII. - Bis(oxazoles) and Tetrazolylammonium Betaines from Bis(vinyl azides)
Saalfrank, Rolf W.,Wirth, Uwe
, p. 969 - 974 (2007/10/02)
Reaction of the geminal vinyl diazide 5 with 1,ω-diamines 6 at -30 deg C leads initially to the crystalline bis(vinyl azides) 8.At 110 deg C, the azides 8 undergo a 3,5 ring-closure reaction.The thus formed bis(azirine) intermediates 20 suffer ring openin
