✦ Synopsis

It has been known that a methanolic solution of mercuric acetate absorbs carbon monoxide to form carbomethoxymercuric acetate 1) . Recently,') the reaction of carbomethoxymercuric acetate with primary and secondary amines was reported, in which the corresponding urethane was formed.

Thallium (III) is isoelectronic with mercury (II) and thallic salt exhibits chemical property similar to that of mercuric salt in the oxymetallation reaction. 3) These facts prompted us to examine the reaction of thallic acetate, amine and carbon monoxide in methanol. Now we found that this reaction yielded urethane as expected. As the amine component, piperidine was used and methyl 1-piperidinecarboxylate was produced.
