WebSo let's go ahead and draw in our benzene rings, like that. So it doesn't really matter how we draw our electrons, so we'll go ahead and do this. So this would be our product. So let's go ahead and put in those electrons. This will be diphenylacetylene. So you can synthesize alkynes from alkenes, or you could synthesize an alkyne from a dihalide.
