Abstract
Organic compounds having functional groups such as aromatic ester, thioester, or carbonate groups are prepared by reacting an organometallic reactant where the metal is gallium, indium, thallium arsenic, antimony, or bismuth, with a suitable second reactant. For example, the ester ##STR1## can be prepared by reacting an organometallic derivative of hydroquinone with p-phenoxybenzoyl chloride.
