Iorn is used to make greener, cheaper, drugs and perfumes

Scientists from Toronto discovered a way to make safer, better catalysis with iron. These catalysts help with the production of alcohol and amines that  help produce alcohol and perfumes.  These productions are usually more environmentally friendly than using any other metals that are toxic. Since iron is the 5th most abundant metal found on the earth it is easier to use it. The metals they used to use were really expensive to obtain and some where toxic. Iron is really inexpensive and can not be toxic. It is good that they are finding ways to make the production of things greener. I think this will really help the environment.
