Abstract
1,3-Cyclopentadiene, excess sodium hydride, and α, α, α′-tribromo-o-xylene react to give 1H-benz[f]indene in a 25% yield. α, α, α′, α′ -Tetrabromo-o-xylene, 2-cyclopenten-1-one, and excess sodium iodide react to from benz[f]indan-1-one. Lithium aluminum hydride reduction of benz[f] indan-1-one and dehydration of benz[f]indan-1-ol forms the title molecule in an overall yield of 40%Keywords
