Alkanethiol reactions on germanium

In addition to Grignard chemistry and hydrogermylation, for which analogs also exist for silicon, there is another type of functionalization chemistry that has been carried out on germanium surfaces that of alkanethiol attachment to H-terminated Ge. Alkanethiols are well known for their use in self-assembled monolayers (SAMs) on gold surfaces. 

Unlike either the Grignard or hydrogermylation reactions, which create a Ge—C bond in the organic attachment to the surface, the alkanethiol reaction creates a Ge—S—C bond configuration upon functionalization. Various 1-alkanethiols react with the hydride-terminated Ge(lll) surface at room temperature, with a well-ordered monolayer resulting from 1 day of exposure to a solution of alkanethiol in
