Application

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]).
