An Mg 4 tetrahedron constitutes the center of the chelate complex anion of 1 , which is obtained in 85% yield from diethyl malonate, methylmagnesium iodide, and oxalyl chloride (1:1:0.25). Acid hydrolysis of 1 affords the free chelate ligand, which is an extremely interesting synthetic building block.
