Organokrypton chemistry describes the synthesis and properties of organokrypton compounds, chemical compounds containing a carbon to krypton chemical bond.
Far fewer such compounds are known than organoxenon compounds. The first organokrypton compound, HKrCCH, was reported in 2003 and made by photolytic insertion of a krypton atom into acetylene.[1] Similar work was then done on diacetylene and cyanoacetylene, producing HKrC4H and HKrC3N.[2] All these were made in matrix isolation and are stable up to 40 K.[3] HKrCCF and HCCKrF have also been experimentally produced in matrix isolation.[4]
Dications generated by dissociative electron ionisation of 2,4,6-trimethylpyridine react with krypton to form the organokrypton cations C8H7NKr2+ and C8H8NKr2+.[5] Reaction of acetylene dications with krypton produced HCCKr2+.[6]
