Abstract
The semi-stabilised ylide, dimethylsulfonium fluoren-9-ide, has been s tudied by variable temperature NMR and found to adopt a conformation i n which the filled orbital on carbon is perpendicular to the lone pair on sulfur. The rotational barrier (Delta G(double dagger)) around the ylide C-S bond is found to be 42.0 +/- 1.0 kJ mol(-1).
