Methoxylation of Singly Bonded 1,4–1′,4′-BnC60–C60Bn Dimer: Preferential Formation of 1,4-C60 Adduct with Sterically Less Demanding Addends and Stability Difference between 1,2- and 1,4-OMe(Bn)C60
摘要:
Methoxylation of the singly bonded 1,4-1',4'BnC60-C60Bn dimer afforded 1,4-OMe(Bn)C-60, a 1,4-C-60 adduct with sterically less demanding addends, as the major adduct. The situation was different from that of direct functionalization of C-60, where 1,2-OMe(Bn)C-60 was obtained as the major product. The reaction was studied with in situ vis-NIR spectroscopy and computational calculations to obtain a better understanding of this unusual regioselectivity. The stability difference between 1,2- and 1,4-OMe(Bn)C-60 was studied.
