摘要:
Diethynylmethanobuckminsterfullerene (1a and C-13-labeled 1b) has been prepared by reaction of the lithium salt of 1,5-bis(trimethylsilyl)-1,4-pentadiyn-3-one (p-toluenesulfonyl)hydrazone (5a/b) with C-60 followed by desilylation and characterized by NMR, IR, UV-vis, and CI-TQMS spectroscopies.
