# can magnesium chloride and iodine react together?

If everything is in a mixture of alcohol and water, would it be possible for magnesium chloride and iodine to react and produce something?

$$\ce{Cl- + 1/2 I2 <=> 1/2 Cl2 + I-}$$ $$\ce{MgCl2 + I2 <=> MgI2 + Cl2}$$ $$\ce{I- + I2 <=> I3-}$$ $$\ce{MgI2 + 2I <=> Mg(I3)2}$$ The amount of products of this reaction though will not be very appreciable, but yes a very literal sense magnesium chloride and iodine will react.
