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]
