摘要:
The fullerendiol C-60(OH)(2)(OOt-Bu)(4) 1 reacts with various arylboronic acids ArB(OH)(2) to form fullerene-containing boronic esters C-60(O2BAr)(OOt-Bu)(4) in up to 95% yield depending on the structure of aryl group. Bis(pinacolato)diboron (B(OCMe2)(2))(2) also reacts with 1 to form C-60(O2BB(OCMe2)(2))(OOt-Bu)(4). The bisboronic ester C-60(O)(O2BAr)(2)(OOt-Bu)(2) was also obtained starting from a tetrahydroxyl fullerene derivative C-60(O)(OH)(4)(OOt-Bu)(2). The fullerenyl boronic esters are moderately stable in air. Single crystal X-ray structure of C-60(O2BPh)(OOt-Bu)(4) was obtained. (C) 2012 Elsevier Ltd. All rights reserved.
