Reactions of vinyl ethers with cobalamins and cobaloximes.
Sir: We recently reported 1 that cobaloximes and cobalamins reacted with vinyl ethers, in the presence of alcohols, to give aceta Is containing cobalt-carbon cr-bonds. On the basis of these, and earlier 2 experiments, we suggested that the reactions proceeded via the intermediary of a Co(lII)-olefin 7r-complex. Schrauzer, et al.,3 then reported that they were unable to confirm our results and c...
متن کاملThe intriguing reaction of aromatic sulfonyl phthalimides with gold surfaces.
We report on a series of arene sulfonyl phthalimides which were prepared and used to modify polycrystalline gold and Au(111) gold surfaces. Three investigated compounds are the p-iodo-, the p-methoxy-, and the p-fluoro-benzenesulfonyl phthalimides. X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV), and scanning tunneling microscopy (STM) studies were used to characterize the modif...
متن کاملFormation of enamides via palladium(II)-catalyzed vinyl transfer from vinyl ethers to nitrogen nucleophiles.
Palladium(II) complexes catalyze the formation of enamides via the formal cross-coupling reaction between nitrogen nucleophiles and vinyl ethers. These vinyl transfer reactions proceed in good yields with amide, carbamate, and sulfonamide nucleophiles, and the optimal catalyst is (DPP)Pd(OCOCF(3))(2) (DPP = 4,7-diphenyl-1,10-phenanthroline).

متن کاملUse of semi empirical method for determination of the activation energy of thermal decomposition of vinyl ethers
In this research, a semi empirical approach has been suggested for calculating the activation energyof unimolecular thermal decomposition of vinyl ethers yielding saturated products. The calculationprocedure is based on the use of molecular mechanics (MM) methods. These methods which involvethe construction of the transition state for a molecule mainly consider the formation of a “HydrogenBridg...
متن کاملdeterminant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
