S. Muthu et P. Maruthamuthu, CHLOROSULPHONYL GROUP AS A NEW FUNCTIONALITY ON FULLERENES - [2-CYCLOADDITION OF CHLOROSULPHONYLISOCYANATE TO C-60(2]), Fullerene science and technology, 4(5), 1996, pp. 1061-1066
The chlorosulphonylisocyanate reacts smoothly with C-60 in xylene unde
r thermal conditions in a [2+2]-cycloaddition fashion to yield the bis
adduct as one of the products in the inseparable reaction mixture. The
reaction product is analysed by FAB-MS, C-13 NMR, FT-IR and HPLC tech
niques. Results show the formation of imino-lactone as one of the favo
urable products.
