摘要：

Alkynes and norbornadiene can be codimerized in a [2 + 2 + 2] Home-Diets-Alder reaction, yielding deltacyclenes. Instead of reduced Co species as used in former cases, Co(II)-complexes activated with Lewis acids such as ZnI2 or ZnCl2 are used to obtain the same products. The [CoI(PPh(3))(2)](+) cation appears to be the catalytically active compound.
