Table 1 A comparison of electrophilic (transfer) chlorination of aromatic donors with 1-Cl+ and 2-Cl+ in CH2Cl2a

|Donor||Productsb||Yield (%)c||t/h||Yield (%)d||t/h|
a In CH2Cl2 solution of 0.015-0.02 M 1-Cl+ or 2-Cl+ SbCl6- and 3 equiv. of aromatic donor at 25 °C. b Products were characterised by GC-MS comparison of authentic samples and quantified by GC using internal standard method (isomer distribution in parentheses). c Excess aromatic donor and 1 recovered quantitatively. d Unreacted aromatic donors recovered quantitatively. A mixture of 2 (20-30%), rearranged spiroketone (50-70%) and several unidentified products were produced.
