A pair of researchers at the University of North Carolina has developed a way to use an organocatalyst to stereocontrol polymerization. In their paper published in the journal Science, A. J. Teator and F. A. Leibfarth describe the process and outline some ways the results could be used. Jeffrey Foster and Rachel O’Reilly with the University of Birmingham have published a Perspectives piece on the work done by the team in the same journal issue.
