We report the functionalization of hydrocarbons by the reactions of arenes and alkenes with (C0) SMnBcat (cat= OK6&)(l),(C0) SReBcat (2), and CpFe (C0) zBcat (3). The activation of unreactive CH bonds has been one of the major goals of transition metal chemistry,'and systems have been discovered that oxidatively add evqn alkane CH bonds. 2 However, few systems activate andfunctionalize any type of hydro~ arbon.'~ J We have found that ...
