Abstract

PURPOSE: To obtain the title compound useful as a plant growth promotor, carcinostatic, or interferon inducer, in high yield without causing polymerization side reactions, by hydrolyzing a specific inexpensive germanium compound.
CONSTITUTION: A compound (C) of formula I or II (X is halogen; R is 1W12C alkyl group) is hydrolyzed under weakly acidic conditions in a short time to give carboxyethylgermanium sesquioxide of formula III in high yield. The amount of water used is 30mol per mole of C. The desired compound can be readily purified without causing polymerization side reactions.
