Epoxidisation of alkenes...
« on: October 29, 2005, 07:57:47 PM »
I had an idea, just now, for a potential synthesis of tetrahydrofuran, which has been proving hard to aqquire nowadays.

How about this.


Take butane, kept liquid.
Oxidise the alkane to an alkene.
 
Epoxidise butene to 1,4-epoxybutene using performic or peracetic acid with a catalytic amount of H2SO4 then reduce the double bond with NaBH4 in a nonpolar solvent with a differing boiling point (and preferably one that doesn't form an azeotrope with THF) or perhaps even catalytic reduction of the double bond with Pd/C 5% and a hydrogen source.

That would be a nice way to make a useful solvent and org. synth precursor starting from OTC butane canisters as sold for blowtorches, lighter refills, camping stoves, etc etc.

What about it?

So behold darkness as our new light
In our darkness we can see
So with others blindness
We take flight.
