A NEW REACTION VESSEL FOR ACCELERATED SYNTHESES USING MICROWAVE DIELECTRIC SUPER-HEATING EFFECTS

Using a thick-walled glass reaction vessel a number of transition-metal organometallic and co-ordination compounds have been synthesised using microwave dielectric super-heating effects. Super-heating by 40-60-degrees-C is maintained by controlling the pressure at 10 atm and results in a decrease in the reaction time required for conventional reflux reactions by a factor of ca. 10(2). Full details of the design of the apparatus, the modification of a conventional microwave oven and the electrical circuitry for the pressure control are
