Two equivalents of this reagent are needed to reduce an ester to a tertiary alcohol.
Donald Cram reacted various aldehydes with these compounds to formulate his namesake rule of asymmetric induction. In the first step of the Ivanov reaction, a carboxylic acid is reacted with two of these compounds to form an unusual carboxylate. Storing these compounds in dioxane or pyridine forces it to undergo a redistribution reaction characterized as the Schlenk equilibrium. Two equivalents of this reagent are needed to reduce an ester to a tertiary alcohol. Reacting formaldehyde with one of them forms a primary alcohol. For 10 points, name these compounds formed when a magnesium atom is inserted into a carbon bromine bond.
