The manufacture of commodity chemicals relies on metals to catalyze, or speed along, the process of making and breaking bonds between lighter elements such as carbon and oxygen. In many cases, the metals are bound to a supporting material to facilitate their separation from the product stream and their subsequent reuse. However, it can be challenging to adopt this approach when the catalyst structure incorporates metalphosphorus coordination. Sun et al. prepared a porous solid by linking phosphine building blocks together. When they introduced rhodium into the structure, the resulting material catalyzed the hydroformylation reaction of octene as well as a free-floating rhodiumphosphine complex.
