In their pioneering work on the lactonisation of an extensive series of co-hydroxycarboxylic acids, Stoll et al. (1934) proposed a procedure for determining the specific rate for cyclisation from the yield of the monomeric lactone at the end of the reaction. To this end they considered the simplified... [Pg.4]
