Literature procedures do not always give consistent results. Sometimes this is the fault of the chemist, and sometimes the fault of the chemistry. This list contains reaction chemistry from the literature that is capricious or difficult to reproduce. This page is a pure reflection of visitor input - it has never been edited internally (disclaimer: the opinions displayed here are not those of the site administrator).
