Abstract
Abstract A new matrix technique developed in our laboratory for the study of bimolecular photochemical processes and the isolation of unstable and air-sensitive organometallic compounds is described. This technique provides a simple and unexpensive method for studying these compounds at room temperature and ambient atmosphere. The matrices used are films of inert polymers, such as polytetra-fluorethylene (PTFE) and polyethylene (PE). We have used this method to study, by means of infrared (i.r.) spectroscopy, the photochemical products and reactions of ironpentacarbonyl with olefins, such as: ethylene, acrylic acid, methylacrylate, nor-bornadiene, butadiene and isoprene; as well as to study the photofragmentation of ironpentacarbonyl. Evidence indicates that, in addition to permitting work, with these compounds at ambient conditions, the method has other advantages over the usual low temperature frozen gas matrices.
