Abstract
The reaction of alkyl halides with three different lithium radical anions, lithium naphthalene (LiN), lithium di-tert-butylnaphthalene (LiDBN), and lithium di-tert-butylbiphenyl (LiDBB), was studied. The reaction of alkyl halides with an excew of LiN, LiDBN, or LiDBB in THF at-78 “C leads to a consistently high yield (96-100%) of reduction products (RH, RLi) with a high degree of formation of RLi (anion trapping 93-95%) in the case of LiDBB. LiDBN ...
