The reactions of CuFe/sup +/ with a variety of hydrocarbons and oxygenated species were studied with Fourier transform mass spectrometry. CuFe/sup +/ is unreactive with linear (C/sub 1/-C/sub 6/) and cyclic (C/sub 3/-C/sub 6/) alkanes. However, it does react with aliphatic alkenes which contain a linear C/sub 4/ unit, chiefly by dehydrogenation. The only aliphatic alkene in which C-C bond cleavage is observed is 2,3,3-trimethyl-1-butene, yielding methane elimination. The secondary reactions of the aliphatic alkenes generally yield more dehydrogenation than the primary reactions. Ion-molecule reactions, collision-induced dissociation, and photodissociation studies yield D/sup 0/(Cu/sup +/-Fe) = 53 +/- 7 kcal/mol and D/sup 0/(Fe/sup +/-Cu) = 56 +/- 7 kcal/mol. Finally, reaction between CuFe/sup +/ and ethylene oxide yields both CuFeCH/sub 2//sup +/ and CuFeO/sup +/, indicating D/sup 0/(CuFe/sup +/-CH/sub 2/) > 79 kcal/mol and D/sup 0/(CuFe/sup +/-O) > 85 kcal/mol, respectively.
