The chemistry of metal-surface molecular interactions is a rapidly expanding discipline. In this article recent work relevant to extending the concepts of organometallic chemistry from mononuclear and cluster compounds or complexes to metal surfaces ib reviewed. The experimental methods important in this organometallic surface chemistry are briefly described, and specific systems are then discussed. Emphasis is placed on the chemistry of carboxylic acids, alcohols, and ketones. The role of oxygen in the synthesis of intermediates is also presented in terms of acid/base interactions. Finally the mechanism of heterogeneous oxidation of alcohols is discussed. Where possible, similarities and differences to metal cluster chemistry are noted.
