AlMe3 can promote the oxidative cyclization of eta2-alkene and eta2-ketone on nickel(0) to give an intriguing nickel-aluminum dinuclear complex having a bridging methyl group, which might be an intermediate for the nickel-catalyzed cycloisomerization of o-allylacetophenone or o-allylbenzophenone.
The method of analysis of nickel, cobalt, and iron base alloys by using the fundamental parameter method, covering the entire concentration range with a single calibration for each element is evaluated. The results obtained were satisfactory and demonstrated that the method can be applied to the analyses of both, major and trace elements using a(More)
The formation of a nickeladihydrofuran by oxidative cyclization of an alkyne and an aldehyde with nickel(0) has been demonstrated; the transformation of the nickeladihydrofuran into an enone by decomposition, a lactone by carbonylation and an allylic alcohol by treatment with ZnMe(2) suggests that nickeladihydrofuran is an important key intermediate in a(More)

We report the synthesis of a series of water-soluble anionic narrow band-gap conjugated polyelectrolytes with a varied density of the ionic functional groups. The charge density is modulated by incorporating the structural units with tetraethylene glycol (TEG) monomethyl ether side chains. These polymers are readily p-doped during dialysis in water.
