Catalytic hydrogenation of the title compound 1 yields 92–95% of ethyl methyl malonate ( 2 ), 3–5% of n ‐propyl malonate ( 3 ), 2–3% of dimethyl 2‐methyl‐1,1‐cyclopropanedicarboxylate ( 4 ), and no 1,1‐cyclobutanedicarboxylate 5 , the formation of which, however, can be induced with a poisoned catalyst.
