A pair of researchers at Purdue University has found a way to use a diatomic Ni-Ni catalyst to synthesize cyclopentenes. In their paper published in the journal Science, You-Yun Zhou and Christopher Uyeda describe their method and outline why they believe cyclopentene products would be useful. Keywan Johnson and Daniel Weix with the University of Wisconsin have published a Perspective piece in the same journal issue describing the work done by the team in Indiana.
