ⓘ Tricyclobutabenzene

Tricyclobutabenzene is an aromatic hydrocarbon consisting of a benzene core with three cyclobutane rings fused onto it. This compound and related compounds are studied in the laboratory because they are often displaying unusual conformations and because of their unusual reactivity. Tricyclobutabenzenes are isomers of radialenes and form an equilibrium with them.

Parent tricyclobutabenzene with 12 h 12 was first synthesized in 1979 in the following sequence: this compound is stable up to 250 °C 482 °C.

In tricyclobutabenzene polyoxygenated with extraordinary lengths of bonds 160 hours for the relations between the two carbonyl groups in the following sequence:

Regular communication of this type is only 148 hours and for comparison the C-C bond in isatin is 154 hours long. On the other hand, no change is recorded in the aromatic bond length alternation.

Similar chemistry was given six times ketone hexaoxotricyclobutabenzene with 12 On 6, which happens to be a novel oxide of carbon. The primary material is Iodo triflate shown below, which is benzotriyne Sinton.
