Organoargon chemistry
Organoargon chemistry describes the synthesis and properties of chemical compounds containing a carbon to argon chemical bond.
Very few such compounds are known. The reaction of acetylene dications with argon produced HCCAr2+ in 2008.[1] Reaction of the CF2+
3 dication with argon produced ArCF2+
2.[2]
The compound FArCCH has been theoretically studied and is predicted to be stable.[3] FArCCF might also be stable enough to synthesise and detect, but probably not FArCCArF.[4] Calculations in 2015 suggest that FArCCH and FArCH3 are stable, but not FArCN.[5] FArCC− should be kinetically stable, as is also expected of the krypton and xenon (but not helium) analogues.[6] HArC4H (for which the krypton analogue is known) and HArC6H have also been predicted as stable.[7] FArCO+ and ClArCO+ should be metastable and might be possible to characterise under cryogenic conditions.[8] Calculations suggest that HArCCF and HCCArF should be stable, and that HNgCCF molecules should be more stable than HNgCCH (Ng = Ar, Kr, Xe); the corresponding krypton species have been experimentally produced, but not the argon species despite an experimental attempt. HCCNgCN and HCCNgNC (Ng = Ar, Kr, Xe) are likewise computed to be stable, but experimental searches for them have failed.[9]
