Photo-promoted one-pot coupling isomerization-codimerization of norbornadiene for efficient synthesis of liquid fuel with density higher than 1 g/mL

exo-exo-Hexacyclo[9.2.1.02,10.03,7.04,9.06,8]tetradec-12-ene (exo-exo) is one of the few liquid fuels with a density higher than 1 g/mL. Currently, exo-exo can only synthesized in bulk via codimerization of norbornadiene (NBD) and quadricyclane...
