Conversion of meso-Stilbene Dibromide to Diphenylacetylene. Alkynes are commonly prepared by the dehydrohalogenation of 1,2-dihalides under basic conditions. Normally, a very strong base such as sodamide (NaNH2) is necessary, but treatment of meso-stilbene dibromide with potassium hydroxide leads to the formation of diphenylacetylene in high ...

DehydrobrominationofMesostilbeneDibromide,GC/MSAnalysis Abstract This experiment carries out the conversion of mesostilbene dibromide to 1,2 diphenylethyne via concerted E2 reactions. Vacuum filtration and recrystallization are then used to extract and purify the desired product which is put through the Bayer and Br2/Ch2Cl2 tests for unsaturation. Other articles where Dehydrohalogenation is discussed: elimination reaction: …for example, is known as dehydrohalogenation; when both leaving atoms are halogens, the reaction is known as dehalogenation.
