n-Butylsodium CH3CH2CH2CH2Na is an organometallic compound with the idealized formula NaC4H9. Like other simple organosodium compounds, it is polymeric and highly basic.[2] In contrast to n-butyllithium, n-butylsodium is only of specialized academic interest.
Preparation
n-Butylsodium is prepared from n-butyllithium and t-butoxysodium.[2]
Properties
In n-Butylsodium, the Na-C bond has ionic character, with a negative charge on the end carbon atom. n-Butylsodium is insoluble in saturated hydrocarbons. It reacts with unsaturated hydrocarbons.[3] Soluble adducts are produced with Lewis bases such as tetramethylethylenediamine or tetrahydrofuran.[2]
Reactions
n-Butylsodium reacts with alkylbenzene or allylbenzene compounds to give new organosodium compounds. With toluene the major product is benzylsodium.[4]
n-Butylsodium reacts with 1-bromonaphthalene to make 1-sodiumnapthalene and 1-bromobutane,[5] but there are few such metathesis reactions.[6]
