Metal‐free regioselective [3+2]‐cycloaddition of 2‐aryl/alkylthiiranes with isothiocyanates, isoselenocyanates and carbodiimides is developed using BF 2 OTf⋅OEt 2 to produce 2‐imino‐dithiolane/‐thiaselenolane/‐thiazolidine frameworks at room temperature. The selectivity, substrate scope and scale up are the important practical features.
