Mechanism of photoisomerization of 1-naphthyl-2-phenylethylenes in organic glasses

Photoisomerization reactions of cis isomers of 1-β-naphthyl-2- phenylethylene, an o-methylated homolog and 1-α-naphthyl-2-phenylethylene in organic glasses at liquid nitrogen temperature were studied. Reactions were followed by changes in UV-absorption spectra of the irradiated samples. Formation of an unstable trans-photoproduct was detected only with the o-methylated homolog. The results are consistent with high regioselective Hula-twist photoisomerization at the benzylic sites of the three compounds examined. Calculated data on relative energies of the conformers of both the cis and the trans isomers are in agreement with the suspected conformational population of the starting materials and the photoproducts.

An efficient Ni-catalyzed synthesis of (E)-olefins using the readily available benzylic alcohol derivatives and arylacetonitriles is described. This transformation should proceed via a tandem process involving nickel-catalyzed cross coupling via C-O activation and subsequent stereoselective E2 elimination.

Naturally occurring d-glucosamine works as an efficient green alternative to phosphines in palladium-catalyzed Heck coupling of aryl and heteroaryl halides. An array of trans-stilbene derivatives, aryl naphthyl alkenes, heteroaryl olefins, and β-aryl-substituted acrylates has been synthesized in short reaction times in moderate to high yields.
Low-valent niobium-mediated synthesis of indenes: Intramolecular coupling reaction of CF3 group with alkene C-H bond

CF3 group of o-alkenyl-α,α,α-trifluorotoluenes underwent intramolecular coupling reaction with the alkene C-H bond under NbCl5/LiAlH4 system. Substituted indenes were obtained in good yields. Copyright
