As compared to the main group hydrides (boron, aluminum, ...) and their derivatives, which are very useful stoichiometric reagents for selective reductions in organic synthesis, hydrides of transition metals provide the chemist with potential catalysts or catalyst precursors. This interesting property is enhanced by the possibility of modifying the coordination sphere, which allows access to a wide variety of hydride complexes with tunable chemical reactivities. Among these, a great variety of carbonylhydridometallates is becoming available and studies of their reactivities continuously appear in the literature. This article reviews the current state of the art as regards the synthesis and reactivity of one of the more promising and versatile carbonylhydridometallates, [HCr(CO) 5 ] − , the simplest anionic hydride derived from hexacarbonylchromium. Its reactivity in stoichiometric reactions is considered first, and then its generation and involvement as a reactive intermediate in catalytic reactions are reviewed.
