Ar. Katritzky et al., Xanthate mediated generation of the benzotriazol-1-ylmethyl radical and its subsequent addition to a variety of olefins, HETEROCYCLE, 54(1), 2001, pp. 301-308
The first generation of the benzotriazol-1-ylmethyl radical (3) is reported
from S-(1H-1,2,3-benzotriazol-1-ylmethyl)-O-ethylcarbonodithioate (1). Sub
sequent additions of radical (3) to a variety of olefins are demonstrated.
