Homogeneous Catalytic Activation of Hydrogen in Aqueous Solutions of Cobaltous Cyanide and Ethylenediamine

Abstract

ONE of the most active systems for the homogeneous activation of molecular hydrogen is an aqueous solution of potassium pentacyanocobaltate-(II), because of the high rate with which it absorbs H2. In the presence of deuterium this system also catalyses the exchange reaction D2—H2O, but with a considerably lower rate than that of the hydrogen absorption. The mechanism of the multiple reactions which take place in these solutions has been recently elucidated1–5.
