R. Gonzalez et al., AN UNUSUAL ADDITION-REARRANGEMENT OF A DIALKOXYCARBENE TO C-60 - EXCLUSION OF METHANOFULLERENE PRODUCTS, Journal of organic chemistry, 61(17), 1996, pp. 5837-5839
The expected (dialkoxymethano)fullerene 3, which would be generated by
the addition of methoxy-[2-(trimethylsilyl)ethoxy]carbene across a ca
rbon-carbon double bond of C-60, was not obtained; the 1,2- and 1,4-di
hydrofullerenes 1 and 2 were isolated instead. The novel compounds 1 a
nd 2 were characterized by C-13- and H-1-NMR as well as FTIR and UV-vi
s spectroscopies. A mechanism for their formation is suggested.
