In the presence of (−)-sparteine or a (+)-sparteine surrogate, organolithiums add to N-alkenyl-N′-arylureas to give benzylic organolithiums in an enantioselective manner. Under the influence of DMPU, ...

Multifunctional films have attracted wide attention in scientific research and engineering applications. Based on thermodynamically driven metathesis reactions of disulfide bonds, a self-healing film ...
