Cyclopropanation of C60 with malonic acid mono-esters
摘要:
Reaction of C-60 With malonic acid mono-esters in the presence of iodine and diazabicyclo[5.4.0]undec-7-ene (DBU) provides the corresponding 61-iodo-1,2-methano[60]fullerene-61-carboxylates. This cyclopropanation of C-60 seems to occur via a carbenoid intermediate. (C) 1997 Elsevier Science Ltd.
