Azete
Acets are unsaturated chemical compounds that have a four-membered ring with a nitrogen atom as a structural element . They belong to the class of the heterocycles , but not the heteroaromatics . Its simplest representative, the acetone , represents the trunk system. The carbocyclic analog is cyclobutadiene .
Azets have conjugated double bonds that form a system of four π electrons . This makes them anti-aromatics , which is why they are present as highly reactive diradicals that are only very weakly mesomeric stabilized .
Acet itself is a highly reactive compound that dimerizes quickly even at low temperatures . To a dimerization to prevent derivatives , the bulky bear bulky radicals, synthesized be. For this example, is suitable tri- tert -butylazet . This can be produced by ring expansion from tri- tert -butylcyclopropenyl azide.
