4-OCTYNE 99% (C005B-023648)

General description

4-Octyne, also known as dipropylethyne can be used as a versatile building block in organic synthesis. The kinetics of the stereoselective semi-hydrogenation of 4-octyne (in tetrahydrofuran) was studied.

Application

4-Octyne, an electron-rich dialkylacetylene, was used in the synthesis of highly substituted 1,3-dienes.
