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.

The kinetics of the stereoselective semi-hydrogenation of 4-octyne in THF by the highly active catalyst [Pd{(m,m'-(CF(3))(2)C(6)H(3))-bian}(ma)] (2) (bian = bis(imino)acenaphthene; ma = maleic anhydride) has been investigated. The rate law under hydrogen-rich conditions is described by r = k[4-octyne](0.65)[Pd][H(2)], showing

Ensemble control has been intensively pursued for decades to identify sustainable alternatives to the Lindlar catalyst (PdPb/CaCO3) applied for the partial hydrogenation of alkynes in industrial organic synthesis. Although the geometric and electronic requirements are known, a literature survey illustrates
