Lithium t-butoxide synthesis

Webn-Butyllithium C 4 H 9 Li (abbreviated n-BuLi) is an organolithium reagent. It is widely used as a polymerization initiator in the production of elastomers such as polybutadiene or styrene-butadiene-styrene (SBS). Also, it is broadly employed as a strong base ( superbase) in the synthesis of organic compounds as in the pharmaceutical industry. WebAvailable materials containing lithium have been developed. Recently it was reported the successful synthesis of Li 2Oby Aaltonen et al [30], which promoted the rapid progress …
