TRANS,TRANS-1,4-DIPHENYL-1,3-BUTADIENE Usage And Synthesis

Chemical Properties

light yellow crystalline powder

Uses

trans,trans-1,4-Diphenyl-1,3-butadiene reacts with Rieke metal complexes of barium and strontium to prepare metal-diene reagents, which is used for the carbocyclization with dichloroalkanes.

Definition

ChEBI: 1,4-diphenylbutadiene is an alkadiene. It has a role as a fluorochrome.

Purification Methods

Its solution in pet ether (b 60-70o) is chromatographed on an alumina-Celite column (4:1), and the column is washed with the same solvent. The main zone is cut out, eluted with ethanol and transferred to pet ether, which is then dried and evaporated [Pinckard et al. J Am Chem Soc 70 1938 1948]. Recrystallise it from hexane. [Beilstein 5 H 676, 9 IV 2319.]
