The fundamental thermodynamic and kinetic factors that influence carbon-hydrogen bond activation at homogeneous transition metal centers were investigated. The project was also directed towards the conversion of hydrocarbons into functionalized products of potential use to chemical industry. Goals during the grant period were (1) to identify new transition metal complexes capable of activating arene and alkane C-H bonds, (2) to quantitatively evaluate the kinetic and thermodynamic stability of these complexes, and (3) to examine routes for functionalization of the activated hydrocarbons. The specific complexes involved in these studies were derivatives of the formulation (C/sub 2/Me/sub 5/)Rh(PR/sub 3/)(R)H, Fe(PMe/sub 3/)/sub 2/(CNR)/sub 3/, Ru(PR/sub 3/)/sub 4/(R)H, and Rh(CNR)/sub 3/H. Functionalization focused upon isocyanide and acetylene insertion reactions. New compounds that activated hydrocarbon C-H bonds include HRe(PR/sub 3/)/sub 5/, HRe(PR/sub 3/)/sub 2/(CNR)/sub 3/, CpRe(Pr/sub 3/)H/sub 4/, CpRe(PR/sub 3/)/sub 2/H/sub 2/, and (eta/sup 6/-C/sub 6/H/sub 6/)Re(PPh/sub 3/)/sub 2/H. 7 figs., 1 tab.
