Barthes, C., Rives, A., Maraval, V., Chelain, E., Brigaud, T., Chauvin, R. (2015). First example of ring carbomer of 1,4-cyclohexadiene. French-Ukrainian Journal of Chemistry, 3(1), 60–65. https://doi.org/10.17721/fujcV3I1P60-65

While a series of carbo-mers of 1,3-cyclohexadienes was reported through the use of a specifically developed synthetic strategy, no example of their 1,4-regioisomers was known. Inspired by the methodology elaborated for the preparation of the 1,3-isomers, the synthesis of the first example of carbo-mer of 1,4-cyclohexadiene is presented. Comparison of physico-chemical properties of this first representative with those of the recently described 1,4-regioisomer, especially UV-vis absorption properties, is also addressed.
