✦ Synopsis

If the mechanism proposed approaches reality, in all experiments, after correction for side reactions, selectivities between 0.500 aind 0.667 should be found. The highest dimerization yield which is theoretically attainable according to this reaction scheme is 66.7 wtO/o. In this case neither E nor F is present. In order to obtain such a high dimerization yield, exclusive formation of D should be aimed at. 'Therefore, if the formation of E can be avoided. not only will the attainable yield be increased, but the formation of the unwanted trimer F will also be prevented. The late of formation of E depends not only on the rate constant but also on the concentration of C (to be denoted [C]). So highest yields and selectivities can be expected when [C] is continuously low, whether by a high rate of reaction ( 2 ) or by a low rate of reaction
