Sec butyl lithium organo
Websec -Butyllithium solution. CH3CH2CH(CH3)Li. Synonyms: Lithium-2-butanide, s-BuLi. CAS … WebSec -butyllithium is more basic than primary organolithium reagents such as n-butyl lithium. It is also more sterically hindered, though it is still useful for syntheses. sec -BuLi is employed for deprotonations of particularly weak carbon acids where the more conventional reagent n -BuLi is unsatisfactory.
