These compounds are of three main classifications. First there are a number of compounds of the transition elements. Many of these are classical or Werner complexes and a few are organometallic compounds. There are also a few procedures dealing with the nonclassical compounds involving metal atom clusters or very strong multi- ple metal-metal bonds. A few more words about one of the latter will be found below. The second large group of com- pounds are those of nontransition elements. In the present vol- ume this group is a rather diverse array, not strongly organized around any principal theme. Although they are transition-metal compounds, I have chosen to place a group of complexes involving low-valent metals coordinated by various phosphorus ligands in a separate cate- gory, since they have an exceptional degree of both practical and fundamental interests. It is only relatively recently that the ability of many other ligands besides carbon monoxide, and most particularly various XsP-type ligands, to stabilize metals in zero or other low formal oxidation states has been generally appreciated. It is now clear, however, that aryl phosphines and phosphites in general have this ability, and a number of compounds have been prepared. Many of these have shown promise as catalysts and are of interest, therefore, industrially as well a.s academically. xi
