A simple, efficient and metal-free route for the synthesis of dissymmetric ketones through Suzuki type cross-coupling reaction has been established. This strategy signifies an attractive, cost-effective and operationally convenient tool for the synthesis of a wide range of dissymmetric ketones. Although conventional routes for the synthesis of ketones have been widely used, the potential challenge

The first highly effective iron-catalyzed carbonylative Suzuki reaction has been developed. Substrates with electron-donating or electron-withdrawing functionality, ortho-substitution, as well as active groups proceeded smoothly, affording desired products in high yields. This protocol is economical, environmentally benign and practical for the synthesis of biaryl ketones.

selective carbonylative Suzuki reactions of aryl iodides with arylboronic acids using an in situ generated nanopalladium system furnished products in high yields. The reactions were performed under ambientconditions and in the absence of an added ligand. The key to success is the addition of pivalic acid, which can effectively suppress undesired Suzuki coupling. The synthesis can be easily scaled up, and
