The first major source of carbanions to be discovered, its utility in organic chemistry arises from the ionic character of its metal- halogen bond.
Addition of it to an ester or lactone yields a tertiary alcohol with two identical alkyl groups. When added to carboxylic acid chlorides, carbon dioxide, and oxiranes, it yields ketones, carboxylic acids, and alcohols, respectively. The first major source of carbanions to be discovered, its utility in organic chemistry arises from the ionic character of its metal- halogen bond. Frequently used in nucleophilic substituion reactions, this is, for 10 points, what compound consisting of an alkane bonded to a magnesium atom bonded to a halide ion, named for its French discoverer?
Addition of it to an ester or lactone yields a tertiary alcohol with two identical alkyl groups.
