1,6-Diphenoxy-2,4-hexadiyne

Uses

1,6-Diphenoxy-2,4-hexadiyne may be used to synthesize the trinuclear derivative with an edge bridging ynenyl ligand on reacting with [Ru₃(μ-H)(μ₃-η2-apyr)(CO)₉] (Hapyr=2-aminopyrimidine).

General Description

1,6-Diphenoxy-2,4-hexadiyne (dimerized phenyl propargyl ether, DPPE) is a disubstituted diacetylene. It is reported to be synthesized by the oxidative coupling of phenyl propargyl ether. Its structural and spectroscopic properties have been analyzed using vibrational spectroscopy and quantum-chemical calculations. It is reported to form an organic hydrogen getter in combination with 5% Pd-CaCO₃. The two crystalline forms of 1,6-diphenoxy-2,4-hexadiyne have been studied.
