I would like to know how to synthesize propyne from propane. I know there is a better answer (much better) than the one I put on my test. I said that propane should be exposed to a bromine solution in the presence of ultra violet light to create 2,2-dibromopropane. I then said to take this compound and expose it to a strong hindered base to create propyne via an E2 mechanism. What is the better way to synthesize propyne, or any allyne from an alkane for that matter? Thanks.
