Abstract
Sustainable chemistry always seeks new synthetic tools. This study brings into light new catalytic properties of triphenylphosphine with the following features: fast, inexpensive, and broad applicability towards dearomative spirocyclizations. Triphenylphosphine has been applied for the synthesis of complex spiro(hetero)cycles in batch and employing continuous flow, a field largely dominated by transition metals. In the cover image, triphenylphosphine has been shown to act as a bridge between sustainable chemistry and the synthesis of complex heterocycles.
