Carbon monoxide is a unique reducing agent that is only gaining popularity in organic chemistry. This review highlights the main approaches to the application of CO as a reducing agent, summarizes and critically analyzes the key trends in this field, and describes the current development prospects. Potentially the most selective and efficient route for the realization of these processes is demonstrated.
