Reaction of 2,2-dibromotricyclo[7.1.01,9.01,3]decane with methyllithium: synthesis of bicyclo[7.1.0]decadiene-1,2 and dibromotriangulane rearrangement
Abstract
Reaction of 2,2-dibromotricyclo[7.1.01,9.01,3]decane with methyllithium gives strained cyclic allene 1 containing an ethenylidene-cyclopropane unit in a nine-membered ring and dimer 6 resulting from a dibromotriangulane rearrangement.
