Alkyl halides and related compounds

Oxirane and chlorine allegedly form complexes C2H4O Cl and C2H4O 3C1 (64HC(19-1)445) at -80 C, but in this and other cases explosions occurred at room temperature, perhaps caused by hypohalites.

We have now established sufficient background to consider briefly the kinetics of reactions in water where apolar solutes are involved. For example, if the hydration characteristics of t-butyl alcohol in water are controlled to a marked extent by the hydration of the apolar t-butyl group, then it is likely that the same state of affairs exists for, say t-butyl chloride and other alkyl halides and related compounds in water. In other words, the hydration properties can be characterized by the general statement that, in the solvent co-sphere, water-water interactions > water-solute interactions, but that in the activation process water-solute interaction will increase. Since for apolar solutes, Cp3 > 0, and assuming that in the transition state, Cp3 0, then a tentative prediction is that ACp < 0 and — —Cp3. 

A large part of the discussions in this chapter was concerned with carbo-cationic [1 l]-telomerizations, i.e., Lewis acid-promoted additions of alkyl halides and related compounds to CC-double bonds with formation of 1 1 products. The relevance of these studies for the initiation of carbo-cationic polymerizations, as described in Scheme 9 (Section III.A), is obvious.
