製備

1-碘丁烷可由1-溴丁烷和碘化鈉反應得到。^[7]

${\displaystyle \mathrm {NaI+C_{4}H_{9}Br\longrightarrow C_{4}H_{9}I+NaBr} }$

1-丁醇和紅磷、碘反應^[8]，或和其它碘化試劑（如氫碘酸^[9]、三苯基膦-碘^[10]、亞磷酸三苯酯-碘^[11]、1-碘-N,N,2-三甲基丙烯胺^[12]）反應，都可以得到1-碘丁烷。

反應

1-碘丁烷是一種烷基化試劑，經過反應可以得到含有丁基的化合物，如和咪唑類化合物反應，得到咪唑鎓鹽^[13]；和苯硫酚反應，得到苯基正丁基硫醚^[14]；和苯乙炔基鋰反應，得到己炔基苯^[15]。

它和硫氰酸鉀在乙醇中回流反應，得到硫氰酸丁酯。^[16]

${\displaystyle \mathrm {C_{4}H_{9}Br+KSCN\longrightarrow C_{4}H_{9}SCN+KI} }$

它和鎂在乙醚中回流，得到格氏試劑正丁基碘化鎂^[17]；和鋅在四氫呋喃中發生類似反應，得到正丁基碘化鋅。^[18]
