Organometallic compound
An organometallic compound is an organic compound that contains carbon bonded to a metal. Some organometallic compounds are highly reactive (dangerously so), while others are relatively stable.
The degree of reactivity of an organometallic compound depends on the degree of ionic character of the carbon-metal covalent bond. Because carbon is more electronegative than metals, a carbon atom bonded to a metallic atom withdraws electrons towards itself. Thus, the carbon atom attains a partial negative charge and the organic group can behave as a carbanion (R3C:-).
A more negative carbon is more reactive than a less negative carbon; therefore, the most reactive organometallic compounds are those containing the most electropositive metals (the alkali metals). An organometallic compound containing a less electropositive metal is less reactive.

increasing ionic character; increasing reactivity
In 1901, the French mathematician-chemist Victor Grignard reported organomagnesium halides (RMgX), now called Grignard reagent, in his doctoral dissertation. He received the 1912 Nobel prize in chemistry for his discovery and Subsequent development of the reactions of these reagents.
One useful reaction of a Grignard reagent is its reaction with a ketone to yield the magnesium salt of a tertiary alcohol, which can be converted to the alcohol by hydrolysis.
