METHOD OF PRODUCING 1-BROMO-2-AZIDO-1,2-DIHYDRO(C-I)[5,6]FULLERENE Russian patent published in 2015 - IPC C07C247/14 

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry and specifically to a method of producing 1-bromo-2-azido-1,2-dihydro(C₆₀-I_h)[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 C₆₀ with bromine azide (BrN₃), generated in situ from N-bromosuccinimide (NBS) and trimethylsilyl azide (TMSN₃) in the presence of triflates of lanthanides and copper M(OTf)_n (M=La, Sm, Yb, Cu; n=2, 3), with molar ratio C₆₀:NBS:TMSN₃:M(OTf)_n=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(C₆₀-I_h)[5,6]fullerene of formula (1) with output of up to 30%.
