Chemical Properties

clear yellow liquid

Uses

3-Pentyn-1-ol was used in the synthesis of 4,4-bis(1-methyl-1H-indol-3-yl)pentan-1-ol.

General Description

Inhibiting effect of 3-pentyn-1-ol on the corrosion of iron in 1M HCl has been investigated. Reaction of 3-pentyn-1-ol with Fe₃(CO)₁₂ in CH₃OH/KOH solution yields closed trinuclear hydridic complex (μ-H)Fe₃(CO)₉(μ₃-η³-[H₃CCC(CH₂)(CH₂)CO]).
