A new helically chiral hexacyclic system, bearing an hydroxymethyl group, was prepared from a simple naphthalene building block in good yield and purity, via a four-step sequence involving palladium-catalyzed Heck couplings and oxidative photocyclizations. Suitable crystals of the latter indicate that its conformation closely resembles that of unsubstituted [6]helicene, whose idealized symmetry is C2. The optical properties of the hexacyclic helicene were investigated and show interesting behavior.
Different reactions of this compound(trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium)Safety of trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium require different conditions, so the reaction conditions are very important.
