Amines are a class of compounds of essential importance in organic synthesis, pharmaceuticals and agrochemicals. Due to the importance of chirality in many practical applications of amines, enantioselective syntheses of amines are of high current interest. Here, we wish to report the development of (...

The discovery of a new class of chemical reaction is uncommon and often leads to new applications and new chemical principles. The formation of amines, ethers, and sulfides by carbon - heteroatom bond-forming reductive elimination has been instrumental in developing practical new routes to aromatic ...
