Mercury—germanium bonds

The allyl-metal bond is usually broken very readily by electrophilic reagents and allyl groups are cleaved from mercury, boron, silicon, germanium, tin, and lead much more easily than are the saturated alkyl groups. Kinetic studies, however, have not been very numerous such studies are reviewed in this chapter. 

Fe(py)2(NO)2]. Interestingly, [Hg Fe(CO)3NO 2] reacts slowly with tris(dimethylamino)phospine (Tdp) in refluxing benzene94 to give first partial then complete substitution of CO (equation 4). Mercury iron nitrosyl complexes are the basis for two routes 03 104 to iron-tin, iron-germanium and iron-lead bonds. These are illustrated in equations (5) and (6).
