TRIFLUOROMETHYL-CONTAINING TRANSITION-METAL COMPLEXES

This chapter examines the current status of the chemistry of trifluoromethyl—containing transition metal compounds where the term “transition metal” had been defined to include the metals of groups. The CF3 ligand is a desirable ligand for many applications in both organic and inorganic chemistry. In transitional metal organometallic chemistry, the substitution of a CF3 group for a CH3 group commonly dramatically improves the thermal, oxidative, and hydrolytic stability of the product. The first trifluoromethyl, containing derivative of a d block element was formed when Mn(CO)5(COCF3) was thermally decarbonylated to give Mn(CO)5(CF3). This chapter reviews some of the early results that were reported in the trifluoromethyl transition metal area. The survey is followed by a discussion of more recent studies, which is presented by group of the periodic table. This chapter focuses the X-ray crystallographic data that have been obtained, while it indicates some aspects of the importance of trifluoromethyl transition metal chemistry and its future. © 1993, Academic Press Inc.
