Abstract

An advanced laboratory experiment that requires students to thoroughly investigate the kinetics, thermodynamics, and the mechanism of the cis–trans isomerization of Mo(CO)₄(PR₃)₂ (R = Et, n-butyl) is presented. The students synthesize the cis complex and then study its conversion to the trans isomer. This experiment illustrates the important relationship between kinetics and thermodynamics and the results emphasize the selfconsistency of the data.

  Abstract:
  Simple modification of a household microwave oven leads to the acceleration of chemical reactions as a result of microwave-assisted reflux. This acceleration is illustrated in the reactions of metal–carbonyls where the M–CO bond is notoriously inert. ...
