    摘要: A process for preparing polyfunctional methylene-bridged compounds is disclosed. A difunctional methylene-bridged compound having acidic protons and having the formula X--CH.sub.2 --X is reacted with an alkali metal in the presence of a disubstituted formamide to provide a methylene-bridged polyfunctional compound having the formula ##STR1## wherein X is an electron-withdrawing group such as --CONH.sub.2, --COOR or --SO.sub.2 R where R is alkyl. The polyfunctional compounds prepared by the process of the present invention are useful in the production of metal complexing or sequestering agents, acidulents, cross-linking agents for polymeric reactions and in applications where a polyfunctional compound is desirably employed.
