Transition metal organometallic reactions have become increasingly important in the synthesis of organic molecules. A new approach has been developed to introduce organometallic chemistry, along with organic and inorganic chemistry, at the foundational level. This change highlights applications of organometallic chemistry that have dramatically evolved in recent decades. With this development, a larger number of students have been reached than would typically be exposed to organometallic reactions. Modules are described that introduce transition metal organometallic compounds and reactions by analogy with thematically similar topics in general chemistry and organic chemistry. These topics are periodically reinforced by incorporation into organic synthesis problems.
