Iron carbonyl complexes with formally monovalent E substituents

2 Iron carbonyl complexes with formally monovalent E substituents 

The iron carbonyl complexes are most easily obtained via reaction of a suitable salt of [Fe(CO)4] and an appropriate dihalo-group 13 element complex X2ER, but reaction of a neutral iron carbonyl compound with (RE) may also be used. The syntheses of the known Fe(CO)4 compounds arc presented in Equations (11)-(14). The R group attached to E can also be a donor ligand such as tris(pyrazolyl)borate (Equation (14)).  

Higher nuclearity derivatives that can be viewed as substitution products of Fe2(CO)9 have been prepared for GaCp, GaSi(SiMe3 3, and InC(SiMe3)3 (Equations All of these adducts show a preferential
