Abstract

Representative examples of the carbonylation reactions of organometallic compounds of non-transition metals with carbon monoxide via transmetallation are summarized from synthetic viewpoint. Such non-transition metals as mercury, boron, thallium, silicon, tin, lead, and tellurium are found to be useful for this purpose, whereas transition metal salts such as palladium(II), rhodium(III), and rhodium(I) are employed stoicheiometrically or catalytically for transmetallation. These combined transmetallation/carbonylation reactions constitute a good method for the preparation of carboxylic acids, their esters, lactones, and ketones regio- and stereo-selectively under mild conditions; i.e., generally with atmospheric pressure of CO and at room temperature.
