Abstract
A resin-based chromium catalyst for performing [6 pi + 2 pi] cycloaddition reactions has been prepared from chloromethylated polystyrene, The catalyst provides cycloadducts in yields comparable to the photochemical and therma l versions of these transformations, and the process is effective with a wi de range of 6 pi and 2 pi reaction partners.
