FIELD: chemistry.SUBSTANCE: invention relates to organic chemistry and specifically to a method of producing 1-bromo-2-azido-1,2-dihydro(C-I)[5,6]fullerene of formula(1), which can be used as a complexing agent, a sorbent and a biologically active compound, as well as in production of novel materials with given properties. The method includes reacting fullerene Cwith bromine azide (BrN), generated in situ from N-bromosuccinimide (NBS) and trimethylsilyl azide (TMSN) in the presence of triflates of lanthanides and copper M(OTf)(M=La, Sm, Yb, Cu; n=2, 3), with molar ratio C:NBS:TMSN:M(OTf)=0.042:(0.042-0.063):0.754:0.042. The reaction is carried out at room temperature (about 20°C) in dry chlorobenzene for 1-4 hours under a current of dry argon without access to daylight.EFFECT: disclosed method enables to obtain 1-bromo-2-azido-1,2-dihydro(C-I)[5,6]fullerene of formula (1) with output of up to 30%.1 tbl, 5 ex |
