Final answer:
An allyl halide treated with t-BuOK typically undergoes nucleophilic substitution, replacing the halide with a tert-butoxide group. Additional reactions might occur depending on the reaction context.
Step-by-step explanation:
When an allyl halide is treated with t-BuOK (potassium tert-butoxide), the likely primary reaction is a substitution where t-Buo- acts as a nucleophile and replaces the halide ion on the allylic carbon (because t-BuOK is a strong base, there may also be elimination reactions leading to alkenes). However, if there's additional context such as cross-coupling reactions or the presence of other reactive groups; then, further reactions could occur. An example could be the formation of cross-coupling products when allyl halides are treated with organometallic compounds in the presence of a palladium catalyst as seen in certain synthetic pathways. The specifics of the product formed depend on the conditions and the specific structure of the allyl halide involved.
