Structure, Reactivity and Applications

The trivalent Co coordination chemistry of amines is simply immense. Amines, both mono- and multidentate, are typically thermally and air stable, often commercially available, easily deriva-tized, and are well matched to the electronic needs of trivalent Co. Space does not permit a discussion of all categories of amines that have been investigated since CCC(1987) nor their limitless permutations when bound to mostly six-coordinate Co. Much of the synthetic and mechanistic work that underpins Co amine chemistry has long been known and will not be restated here. The emphasis here will be on novelty rather than breadth. That is, recent innovative aspects of the structure, reactivity, and applications of selected, but representative, collections of these simple but ever-present compounds will be our focus. 

The synthesis of tropones, tropolones, and tropylium salts with fused heterocyclic rings forms the first part of a projected two-chapter sequence by G. Fischer (Leipzig, Germany). It is planned that the structure, reactivity, and applications of these compounds will be discussed in a further contribution in a subsequent volume.

There has been a recent comprehensive review written on Group 10 metallacycles12 and only the more recent and relevant papers in this group will be covered. In this present review, we will discuss particularly the synthesis, structure, reactivity and applications of metallacycles.
