1-Lithio-2-alkyl-1,2-dihydropyridines, easily formed from addition of (n- or t-)BuLi to pyridine, have been compared; the steric bulk of the branched alkyl substituent enforces lesser oligomerization, thus enhancing alkane solubility making it an amenable, convenient lithium hydride transfer reagent in non-polar, aliphatic media.
