Transition metal catalyzed dehydrogenative C-C and C-N bond formation is a powerful synthetic method that allows for the formation of new carbon-carbon (C-C) and carbon-nitrogen (C-N) bonds through the removal of hydrogen gas (H2) from the starting materials. This method is a key tool in modern organic synthesis, as it allows for the construction of complex organic molecules from simple starting materials in a single step.

Transition metal catalyzed dehydrogenative C-C and C-N bond formation is a powerful synthetic method that allows for the formation of new carbon-carbon (C-C) and carbon-nitrogen (C-N) bonds through the removal of hydrogen gas (H2) from the starting materials. This method is a key tool in modern organic synthesis, as it allows for the construction of complex organic molecules from simple starting materials in a single step. The process of transition metal catalyzed dehydrogenative C-C and C-N bond formation typically involves the use of a transition metal catalyst, such as palladium (Pd), nickel (Ni), or iron (Fe), in combination with a suitable oxidant, such as oxygen (O2) or a peroxide. The catalyst and oxidant work together to remove hydrogen atoms from the starting materials, creating new C-C or C-N bonds in the process. One example of this type of reaction is the dehydrogenative coupling of arylamines and ketones to form aryl ketones, which is catalyzed by a palladium complex. In this reaction, the palladium catalyst coordinates with both the arylamine and the ketone, promoting the removal of hydrogen from the amine and the ketone, and facilitating the formation of a new C-N bond between the amine and the ketone. Another example is the dehydrogenative coupling of alcohols to form ketones, which is catalyzed by a ruthenium complex. In this reaction, the ruthenium catalyst activates the alcohol by coordinating with the oxygen atom, promoting the removal of hydrogen from the alcohol, and facilitating the formation of a new C-C bond between the alcohol and the ketone. Transition metal catalyzed dehydrogenative C-C and C-N bond formation is a versatile and powerful tool in synthetic organic chemistry. It offers a way to efficiently construct complex organic molecules from simple starting materials, and it can be used to create a wide range of C-C and C-N bonds, including those that are difficult or impossible to form using traditional synthetic methods. One of the major advantages of this method is its efficiency. By eliminating the need for pre-functionalization of the starting materials, it allows for the construction of complex organic molecules in fewer steps, and with fewer waste products. This makes the process more environmentally friendly and sustainable. Another advantage is the selectivity of the reaction. By carefully choosing the catalyst and reaction conditions, chemists can control the regioselectivity and stereoselectivity of the reaction, allowing for the formation of specific C-C and C-N bonds, and minimizing the formation of unwanted byproducts. Transition metal catalyzed dehydrogenative C-C and C-N bond formation has also been applied to the synthesis of natural products, pharmaceuticals, and other biologically active molecules. For example, the synthesis of the anti-tumor drug dasatinib has been achieved using this method. In conclusion, transition metal catalyzed dehydrogenative C-C and C-N bond formation is a powerful and efficient method for the construction of complex organic molecules from simple starting materials. It offers a versatile and selective approach to the formation of new C-C and C-N bonds, and has the potential to revolutionize synthetic organic chemistry
