Abstract: In this paper advances in gaseous transition-metal ion chemistry are briefly introduced in five aspects: (1)general research method; (2)reaction types; (3)the law of the reaction (with hydrocarbons; alcohols, haiohydrocarbons, amines; nitriles; carboxydes; compounds of containing functional groups; metal carbonyls; nitro-compounds and nitrous acid esters et al. ); (4)collectoin of thermodynamic data; (5)study on machanisms.
