Promoting non-transition metal alkylation with organic halides in the presence of binary systems based on an organometallic compound and a transition metal compound: VI. Effect of various additives on the rate of the steady-state process

Аннотация

The effect of various additives such as transition and non-transition metal oxides, hydroxides, and salts on the rate of steady-state alkylation of commercial zinc powder with ethyl bromide in the presence of ethylzinc bromide–copper(I) iodide binary system has been studied. Most of the examined compounds either do not affect the reaction rate or reduce it. Only addition of zinc(II) bromide, zinc(II) hydroxide, and water appreciably accelerates the process. Mechanism of action of the additives is discussed.
