converted to 2,4-, 2,5-, and 2,7-dinitro-9-fluorenyl p-toluenesulfonates (IVa, IVb, and IVc) through the corresponding 9-diazo compounds (IIIa, IIIb, and IIIc). These diazo compounds were converted directly to the three dinitro-9-fluorenols (VIa, VIb, and VIc) and 9-fluorenyl acetates (Va, Vb, and Vc).Rates of acetolysis of the three p-toluenesulfonates (IVa, IVb, and IVc) were measured in glacial acetic
