A simple route for the preparation of methylene-bridged bis-1,3-dicarbonyl compounds was achived through a cleavage of C—N bond of tertiary amines. In this reaction, tetramethylethylenediamine (TMEDA) was used as the methylene source, and cuprous iodide as catalyst under aerobic condition. The substrates bearing different substituents were tolerated well and afforded the corresponding products with moderate to good yields.

Key words: air, tertiary amines, C—N bond cleavage, methylene-bridged compounds
