Transition-metal carbonyl derivatives of the germanes. Part 9. Reactions of tetracarbonyldi(methylgermyl)iron with some covalent halides
Abstract
The reactivity patterns of [Fe(CO)4(GeMeH2)2](1), with covalent halides have been established from 1H n.m.r., i.r., and mass-spectral studies. Halogenation by milder reagents such as SiCl4 is stepwise and alternate at each germanium. The more reactive hydrogen halides substitute and then cleave Fe–Ge bonds. The germyliron system is intermediate in its tendency to cleavage between the germyl-manganese and the -cobalt carbonyls. Rearrangement to cyclic compounds [{Fe(CO)4(GeMeClxH1-x)}2] is observed after longer reaction times.
