G. Dyker et A. Thone, Palladium catalyzed coupling reactions of diiodoarenes with allylic and homoallylic alcohols, J PRAK CH C, 341(2), 1999, pp. 138-141
A sequential transformation consisting of a twofold Heck reaction of 1,2-di
iodobenzene (14) with allyl alcohol (2) followed by an intramolecular aldol
condensation is suitable for the construction of the benzocyclohept-2-ene-
2-carboxaldehyde (15). Under the same reaction conditions 1,8-diiodonayhtha
lene (7) lends to 1-acenaphthenyl-methanol (6), 2-(1-acenaphthenyl)-ethanol
(8), 1-(1w-acenaphthenyl)-ethanol (11), 5-(1,8-naphthalena)-nonan-2,8-dion
e (12) and 5-(1-naphthyl)-3-methylpentan-2-on (13) mainly.
