“Aromatization of tetrahydrocyclopropa[α]naphthalenes: An alternative synthesis of 1H-Cyclopropa[α]naphthalene”
Helv. Chim. Acta 1989, 72, 1627-1638.
1H-Cyclopropa[a]naphthalene (1a) is accessible via reduction of the dichloro compound 1c with LiAlH4/AlCl3. Several derivatives of tetrahydrocyclopropa[a]naphthalene were synthesized. However, contrary to their 1,1-dihalogeno analogues, they afforded no cycloproparenes upon attempted aromatization.
