Flash Vacuum Thermolysis of Four Membered Rings Containing Nitrogen Atom. Part I. Thermal Decomposition of Azetidines

Bartnik, R.,Lesniak, S.,Galindo, A.

, p. 719 - 726 (2007/10/02)

The addition of acetic acid or hydrogen chloride followed by the nitrosation of azabicyclobutanes produced 1-nitroso-3-acetoxy-(or -chloro)azetidines.The thermal decomposition of these compounds under FVT conditions was studied.The cycloreversion of azetidine ring, entirely regioselective, was observed.Key words: azabicyclobutanes, azetidines, flash vacuum thermolysis
