Group IIIB organometallics

Recently, groups experienced in Group IVB chemistry started research programs with the objective to study Group IIIB organometallic chemistry in relation both to early transition metals and f-elements. Thompson and Bercaw recently published their results on Cp ScR compounds [33]. Our work on Cp YR chemistry will be reported in the following section. In relation to this, relevant literature data on organo-yttrium chemisty will be mentioned first. 

Organometallic compounds of group-IIIB elements in the M(I1) state are unstable even when they incorporate electron-releasing groups, and few have been prepared.

In this section, we will discuss organometallic derivatives of zinc, cadmium, mercury, and indium. The group IIB and IIIB metals have the d10 electronic configuration in the 2+ and 3+ oxidation states, respectively. Because of the filled d level, the 2+ or 3+ oxidation states are quite stable, and reactions of the organometallics usually do not involve changes in oxidation level. This property makes the reactivity patterns of these organometallics more similar to those of derivatives of the group IA and IIA metals than to those of derivatives of transition metals with vacancies in the d levels. The IIB metals, however, are...
