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.

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

We present a study that maps out chemical bond formation between a Pt-inked probe and a single 1,3-cyclohexadiene (1,3-CHD) molecule on Si(100). By separating the mechanical and electronic contributions to the current during the approach to contact, we show that

We demonstrate the use of shaped ultrafast laser pulses in the deep ultraviolet to control the ring opening isomerization of 1,3-cyclohexadiene to form 1,3,5-hexatriene. The experiments are performed with a gas phase sample and the isomerization yield is probed with
Chemo-, regio-, and stereoselective cobalt-mediated [2+2+2] cycloaddition of alkynyl boronates to alkenes: 1,3- and 1,4-diboryl-1,3-cyclohexadienes.
