See these articles. They are very interesting and useful, for me:
"A tentative rationalization of microwave effects in organic synthesis according to the reaction medium, and mechanistic consideration."
L. Perreux, A. Loupy, Tetrahedron, 57:9199-9223(2001)
"Microwave assisted organic synthesis - a review"
P. Lidstroem, J. Tierney, B. Wathey, J. Westman, Tetrahedron, 57:9225-2983(2001)

AFOAF saw one of these robo-wavejobbers in action and demoed it and said it was the shit
