Azete

Azete are unsaturated chemical compounds which have a structural element of a four-membered ring containing one nitrogen atom. They belong to the class of heterocycles, but not the heteroaromatics. Your simplest representative, the hairpieces, represents the root system. The carbocyclic analogue is cyclobutadiene.

Azete possess conjugated double bonds, forming a system of four π electrons. Hereby they are among the antiaromatics why they exist as highly reactive diradicals, which are very weak resonance-stabilized.

Azet itself is a highly reactive compound, the dimerized rapidly even at low temperatures. Order to prevent dimerization derivatives which bear sterically bulky radicals, are synthesized. You should create it as tri -tert- butylazet. This can be prepared by ring expansion of tri -tert- butylcyclopropenylazid.
