1 The kinetics on the displacement reaction of tri-isobutyl aluminum with ethylene catalyzed by zerovalent cobalt complex has been studied.

2 The present dissertation deals with the displacement reaction of ethylene and high alkyl aluminum compounds.

3 In the experiments, the acceleration and displacement reaction of the wooden structure houses were obtained by the role of transmitting several different peaks of the seismic waves to it.

4 The total and subsidiary reactions of the classical Fe-Cu displacement reaction are investigated and defined.

5 However, alkyl-substituted propargylic dithioacetals could be synthesized by the displacement reaction of the corresponding terminal alkynes with alkyl iodides.
