1. A method of accelerating organic reactions that include a gas phase reactant, the method comprising:
- introducing a microwave transparent reaction vessel containing at least one reactant into a microwave cavity;
purging the reaction vessel;
charging the reaction vessel with a gas phase reactant; and
applying a continuous single mode of microwave radiation within the cavity and to the vessel and its contents until the reaction proceeds to a desired yield.

Abstract
A method of accelerating the hydrogenation of organic compounds is provided. The method includes positioning an microwave transparent reaction vessel containing at least one reactant suitable for hydrogenation in a microwave cavity, purging the reaction vessel, charging the reaction vessel with hydrogen gas, and applying a continuous single mode of microwave radiation within the cavity and to the vessel and its contents for a time sufficient to effect a chemical change in the reactants.
