Chlorine as solvent
Chlorine condenses at -34 Celsius, and freezes at -102 Celsius.
What is it like as a solvent? As reaction environment?
Chlorine is a symmetric molecule, which suggests a low polarity. So what dissolves in chlorine? What reaction mechanisms are favoured?
Also, HCl condenses at -85 Celsius and freezes at -115 Celsius. It is a polar molecule, but the liquid is said to be not very polar.
Thus between -85 and -102 Celsius, Cl2 and HCl are both liquids. Are they miscible or not?

I would expect than, in the absence of reducing agents, chlorine would be a very non-polar solvent, much like butane. I also don't imagine it would
be a particularly interesting solvent, apart from the high oxidizing power and sheer difficulty in working with it.
I'd guess that the two liquids would be miscible. But that's just a guess.

BCl3 condenses at +13 C and stays liquid down to -108 C. It is trigonal planar, thus nonpolar, and unlike AlCl3 does not
dimerize.
How readily does BCl3 complex with Cl2? Would it form a polar Cl+-BCl4-, which might
precipitate out of low polarity Cl2? Or are Cl2 and BCl3 miscible?
