摘要：

The formation of mono and bis adducts of Cu+ ion with alkane molecules has been studied using a multiquadrupole mass spectrometer. Alkali cations do not react under those conditions, in agreement with a stronger bond involved with Cu+. Kinetic study of the association of Cu+ with cyclohexane showed that Cu+ reaction is first-order relatively to cyclohexane, indicating a remarkably long lifetime of the intermediate excited adduct. Rigidity of the alkane molecule decreases the stability of the corresponding adduct.
