Organogermanium carboxylates

Since the first synthesis of organogermanium nitrogen derivatives it was found that the Ge—N bonds display high reactivity, especially an easy protolysis with water, alcohols, phenols, carboxylic acids, hydrohalic acids, SH-, NH-, PH- and CH-acids, etc36,37,77,346,347. All these reactions were initiated by electrophilic attack of the reactant proton on the nitrogen atom76,468,469. 

Organogermanium trihalides containing oxygen in form of hydroxy, carbonyl, carboxyl groups or their derivatives are compiled in this chapter. The compounds are prepared by methods from the following scheme.
