Cover Feature: Isolable 1‐Butene Copper(I) Complexes and 1‐Butene/Butane Separation Using Structurally Adaptable Copper Pyrazolates (3/2021)

The Cover Feature shows that 1-butene molecules can penetrate into a dense crystalline solid and drive the transformation of planar trinuclear fluorinated copper(I) pyrazolate complexes toward boat-shaped, dinuclear copper-butene adducts. The chemistry of these complexes with 1-butene is also examined in solution, and a comparison with analogous adducts formed with ethene and propene is provided. More information can be found in the Full Paper by M. G. Cowan, H. V. Rasika Dias, and co-workers.
