Diphenylcopperlithium and dimethylcopperlithium react differently with the same primary neopentylic tosylate ester. Several secondary neopentylic tosylates react with organocopperlithium reagents to give olefins via a concerted anti-1,2-dehydrosulfonation. When anti-elimination is not possible, skeletal rearrangement occurs.
