[Transition metal activation and functionalization of carbon-hydrogen bonds]. Progress report, December 1, 1992--November 30, 1993
A method was developed for synthesizing a new complex for studying C-H activation, (HBPz*{sub 3})Rh(CNCH{sub 2}CMe{sub 3})(PhN=C=NCH{sub 2}CMe{sub 3}). This complex loses the carbodiimide ligand, thereby serving as a precursor for a 16-electron Rh(I) fragment which activates (via oxidative addition) a wide range of aromatic and aliphatic C-H bonds. Mechanism of activation of benzene by this fragment was studied. Reaction of [Tp`Rh(CNR)] fragment with aliphatic hydrocarbons was also studied. A study of C-H bond activation by the complex MnH{sub 3}(dmpe){sub 2} was completed. Reactions of [Ru(dmpe){sub 2}] with several small molecules were also investigated. Effects of fluorine substituents on aromatic ring on C-H activation were looked at. Studies of {eta}{sup 2}-arene coordination with [(C{sub 5}Me{sub 5})Rh(PMe{sub 3})] were completed; studies of reaction of this complex with 1,3-disubstituted benzenes are in progress.
