WebThe chiral ligands have played indispensable roles in the transition-metal catalyzed asymmetric reactions, which could significantly modulate the reactivities and enhance the stereoinduction.1 Therefore, the design and develop-ment of new chiral ligands is crucial in the development of metal catalyzed asymmetric catalysis. Web2 days ago · This work introduces the chiral memory effect on the celestial sphere that measures the permanent change of electromagnetic fields by spin-dependent processes in bulk. Unlike the conventional memory effect based on the permanent soft shift in the gauge field itself, it is a permanent change in its spin angular momentum. The concept …
