Reaction of Organocuprates Substitution of allylic halides • Alkylation of allylic halides with organocuprates usually produces mixtures of products due to competing S N 2 and S N 2’ reactions. • Substitution with complete allylic rearrangement (S N 2 reaction) is observed with R<strong>Cu</strong>·BF 3 as the alkylating agent.
Reaction of Organocuprates Reaction of vinyl halides • Coupling of alkenyl bromides or iodides with organocuprates proceeds with high stereoselectivity. 1,2-Addition to aldehydes and ketones • Organocuprates undergo 1,2-additions to aldehydes, ketones, and imines. Reactions are often highly diastereoselective.
