A reactor has been designed specifically to conduct lithium aluminum hydride reductions in flow. The reactor readily accommodates strong hydrogen gas evolution and allows strict control over the combination of starting material and reductant, the reaction itself, and quenching, all of which are conducted within the confines of the reactor leading to a safe process.
