Application

1,3-Cyclohexadiene can undergo:
  • C-C coupling with aromatic alcohols via iridium-catalyzed hydrogen auto-transfer and with aldehydes via transfer hydrogenation mediated by isopropanol to form carbonyl addition products.
  • Living anionic polymerization with n-BuLi/TMEDA system to form polycyclohexadiene.
  • Platinum-catalyzed silaboration to form (1R,4S)-1-(dimethylphenylsilyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-cyclohexene.
  • Aerobic palladium-catalyzed 1,4-diacetoxylation in the presence of cobalt tetra(hydroquinone)porphyrin as an electron transfer reagent.

Under hydrogen autotransfer conditions employing a catalyst derived from [Ir(cod)Cl]2 and BIPHEP, 1,3-cyclohexadiene (CHD) couples to benzylic alcohols 1a-9a to furnish carbonyl addition products 1c-9c, which appear as single diastereomers with variable quantities of regioisomeric adducts 1d-9d. Under related transfer

Benzoyl nitroside (5) was generated in solution by laser photolysis of 3,5-diphenyl-1,2,4-oxadiazole-4-oxide (4) and studied by time-resolved infrared spectroscopy. The second-order rate constants for reaction of 5 with diethylamine and 1,3-cyclohexadiene were determined to be (1.3 +/- 0.5) x 10(5)

An efficient and green method for the synthesis of highly substituted cyclohexa-1,3-diene, polyhydroindene, polyhydronaphthalene, isochromene, isothiochromene, and isoquinoline derivatives has been developed. The synthesis was achieved by using a multicomponent procedure in ionic liquid media. The features of this procedure

Herein we report the first all-carbon N-heterocyclic carbene-catalyzed (4 + 2) cycloaddition. The reaction proceeds with α,β-unsaturated acid fluorides and silyl dienol ethers and produces 1,3-cyclohexadienes with complete diastereocontrol (dr >20:1) while demonstrating a new type of reaction cascade exploiting

The first CH/π solute-solvent interaction of C(60) was evidenced by the kinetic solvent effects in the Diels-Alder reaction with 1,3-cyclohexadiene based on the evaluation of linear free energy relationship of log k(2) with empirical solvent polarity and basicity parameters, E(T)(30)
