1. A method of accelerating organic reactions that include a gas phase reactant, the method comprising:

  • conducting a hydrogenation reaction selected from the group consisting of olefin hydrogenation, alkyne hydrogenation, carbobenzyloxy deprotection, and reductive amination, using the steps of;

    introducing a microwave transparent reaction vessel containing an organic compound to be hydrogenated into a microwave cavity;

    purging the reaction vessel containing the organic compound to be hydrogenated;

    charging the reaction vessel with hydrogen gas in an amount that is at least stoichiometric with respect to the amount of the organic compound to be hydrogenated;

    applying a continuous single mode of microwave radiation within the cavity and to the vessel and the organic compound in the vessel until the organic compound is hydrogenated to a desired yield; and

    venting the vessel at the completion of the hydrogenation reaction.
