Hollow‐Shell‐Structured Nanospheres: A Recoverable Heterogeneous Catalyst for Rhodium‐Catalyzed Tandem Reduction/Lactonization of Ethyl 2‐Acylarylcarboxylates to Chiral Phthalides

Chiral organorhodium-functionalized hollow-shell-structured nanospheres were prepared by immobilization of a chiral N-sulfonylated diamine-based organorhodiu...
