The Molecular Mechanism of Action of Dimethyl Sulfoxide

7 9: Summary of Reactivity of Haloalkanes

In high dielectric ionizing solvents such as water dimethyl sulfoxide acetonitrile S N 1 and E1 products may be observed Rapid S N 2 substitution for 1 halides E2 elimination will compete with substitution in 2-halides and dominate in the case of 3-halides In high dielectric ionizing solvents S N 1 and E1 products may be formed
