Preparation and characterisation of two [70]fullerene diols, C70Ph8(OH)2
Abstract
Reaction of a CCl4 solution of C70Ph8 with air in the presence of light and [70]fullerene gives a bis-lactone C70Ph8O4 (44%), together with a 1,2-diol, C70Ph8(OH)2, 19,26,33,37,45,49,53,63-octaphenyl-7,8,19,26,33,37,45,49,53,63-decahydro[70]fullerene-7,8-diol (40%), 1 of Cs symmetry. This latter is also produced from reaction of a dichloromethane solution of C70Ph8 with
