As many refrigerants are being replaced due to environmental concerns, it seems to me that isoprene could be safe and inexpensive but has not been used. Am I missing something?
Its higher boiling point can be compensated by working slightly below atmospheric pressure.

Foregoing physical properties, my first concern would be the potential for this to polymerize at some of the elevated temperatures in contact with some of the more common metals, metal oxides, oils, etc..

Ordinarily, you'd want the refrigerant to be relatively nonreactive, rather than a material that has to be stabilized to be stored, or special care taken to prevent its contact with something that could help it polymerize, possibly in an uncontrolled fashion.

It's been a long, long time since that Organic lab, but I still remember how 'prenes' twitchy double bonds had a very nasty habit of polymerising to intractable 'Brown Gunge'...
Don't go there.
