- Ester derivative industrial production process
-
The present invention provides an ester derivative industrial production process which is characterized in that a monoester or a diester derivative is obtained by reaction of a compound A and carbon monoxide or carbon dioxide under the effect of a catalyst; the production process is simple, and is different from complex production ways and demanding production conditions in the prior art, and the target ester derivative product can be synthesized by one step. The production process and synthetic routes are optimized, so that the production process is fewer in side effects, convenient in post treatment, mild in production conditions, and suitable for industrial production modes.

- Hydrogenolysis of Small Cycloalkanes, XVII. - Catalytic Hydrogenation of Dimethyl Bicyclobutane-2,2-dicarboxylate
-
Catalytic hydrogenation of the title compound 1 yields 92-95percent of ethyl methyl malonate (2), 3-5percent of n-propyl malonate (3), 2-3percent 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.
