Kinetics and Mechanisms of Substitution Reactions of Dicobalt Octacarbonyl
Reaction of Co(,2)(CO)(,8) with bases of low nucleophilicity, e.g. P(CH(,2)CH(,2)CN)(,3) or P(O-i-Pr)(,3), or large steric requirement, e.g. P(t-Bu)(,3), results in formation of substituted dinuclear species of the form Co(,2)(CO)(,7)L and Co(,2)(CO)(,6)L(,2). These reactions exhibit first order …

Physical Properties of Magnetic Macromolecule-Metal and Macromolecule-Metal Oxide Nanoparticle Complexes
… were prepared by the thermolysis of dicobalt octacarbonyl in two block copolymer micellar systems, wherein the copolymers were precursors to graphite or silica. Subsequent heat treatment of the samples at 600-700oC was conducted to condense the polymer coating around the cobalt …
