In this study, a one-pot two-step Pd-catalyzed reductive eliminate between acetyl naphthalene derivatives, tosylhydrazide, and arylhalide, affording substituted 1(or 2)-(1-phenylvinyl)naphthalene in moderate-to-excellent yields, was reported. Notably, solvent played a crucial role in the coupling of 1-acetyl naphthalene derivatives (toluene) or 2-acetyl naphthalene derivatives (1, 4-dioxane) as starting

Electro-reduction of 1-acetylnaphthalene in alkaline solution gave the substituted tetrahydro-1,4-methano-3-benzoxepin (I) and not the expected pinacol. The structure of this compound is deduced from its spectral properties and its conversion into 1-(4-acetyl-1-naphthyl)-1-(1-naphthyl)ethane (II) on treatment with acid. The reduction of 1-acetylnaphthalene in neutral medium also gave (I). In acid medium

AbstractA novel route to 2,2‐diarylvinyl phenyl selenides is reported by dehydration of the corresponding 2,2‐diaryl‐2‐hydroxyethyl phenyl selenides, prepared by oxyphenylselenenylations of the corresponding 1,1‐diarylethylenes, upon treatment with p‐toluenesulfonic acid.
