中文摘要the reactions of dianionic c-60 with organic halides, which have been studied extensively in benzonitrile (phcn), are revisited in a different solvent medium, n,n-dimethylformamide (dmf), by using arch2br (ar = ph, c6h4ch3, c6h4br). interestingly, instead of the 1,4-r2c60 adducts, which are the typical products when the reactions are carried out in phcn, the 1,2-dihydro[60]fullerenes (1,2-hrc60) have been obtained as the major products in dmf, except for the case of o-ch3c6h4ch2br probably due to the steric effect. the obtained 1,2-dihydro[60]fullerenes have been characterized with single-crystal diffraction, h-1 and c-13 nmr, high-resolution mass spectrometry (hrms), and uv-vis. further examination with deuterated reagents including plicd(2)br, dmf-d(7), and d2o has revealed that the fullerenyl hydrogen of 1,2-dihydrofullerenes originates from traces of water residue in dmf. when the reaction is re-examined in phcn with the addition of an excessive amount of water, the yield of 1,2-dihydrofullerene increases significantly, but is still lower compared with that obtained in dm f, demonstrating a considerable solvent effect on the reactivity of c-60(2-). a possible mechanism accounting for such a difference is proposed. the work has presented an alternative protocol for effective preparation of 1,2-dihydro[60]fullerenes, and may also provide clues toward a better understanding of the proton transfer process for anionic coo-mediated reducing, reactions involving h2o.
