Researchers dramatically simplify and streamline organic chemical synthesis
For the first time researchers discovered a simple and highly efficient way to produce certain kinds of organic compounds. The team from the Department of Chemistry at the University of Tokyo report their new method—which uses a novel iron catalyst—can not only simplify organic synthesis but would greatly reduce costs and cut down on waste products. This could have huge implications for industries
