a Ring-opening with N-Me aniline 2. b Empirical reactivity scale of QPrS and EPrS 1a–1f. c Ring-opening with hydroxylamines 4a–4e and tosylamide 6. The isolated yields were given.a Product isolated as the corresponding phosphine oxide, after treatment of the crude with H2O2; b nd not detected - although full conversion of the phosphiranium substrate was observed.
