An organometallic compound with the chemical formula C 4 H 9 Li. It is obtained by reacting bromobutane with metallic lithium in ether. It is a colorless liquid. Depending on the position of the carbon to which the lithium is bonded, four isomers are known: primary ( n- and iso), secondary, and tertiary, in which order the basicity increases. It is more basic than the corresponding Grignard reagent, and is important as a reagent for abstraction reactions of acidic hydrogen in organic compounds.

化学式C4H9Liで表される有機金属化合物。ブロモブタンにエーテル中で金属リチウムを作用させて得られる。無色の液体。リチウムの結合する炭素の位置によって,第一(n‐およびイソ),第二,第三の4種類の異性体が知られており,この順序で塩基性が強くなる。対応するグリニャール試薬よりも塩基性が強く,有機化合物中の酸性水素の引抜反応を行う試剤として重要である。【友田 修司】
