    • Process for functionalizing saturated hydrocarbons comprising: (a) reacting said saturated hydrocarbons of the formula: R1H wherein H represents a hydrogen atom; and R1 represents a saturated hydrocarbon radical, with a metal complex of the formula: CpRh¢P(R2)3!H2 wherein Cp represents a cyclopentadienyl or alkylcyclopentadienyl radical; Rh represents a rhodium atom; P represents a phosphorus atom; R2 represents a hydrocarbon radical; H represents a hydrogen atom, in the presence of ultraviolet radiation to form a hydridoalkyl complex of the formula: CpRh¢P(R2)3!(R1)H (b) reacting said hydridoalkyl complex with an organic halogenating agent such as a tetrahalomethane or a haloform of the formulas: CX'X''X'''X'''' or CHX'X''X''' wherein X', X'', X''', X'''' represent halogens selected from bromine, iodine or chlorine atom, at a temperature in the range of about -60.degree. to -17.degree.C to form the corresponding haloalkyl complex of step (a) having the formula: CpRhPMe3RX; and, (c) reacting said haloalkyl complex formed in (b) with halogen (X2) at a temperature in the range of about -60.degree. to 25.degree.C (i.e., ambient) to form a functional haloalkyl compound.
