- Oxidatively intercepting heck intermediates: Pd-catalyzed 1,2- and 1,1-arylhalogenation of alkenes
-
This communication describes the development of two Pd-catalyzed reactions for the arylchlorination of diverse α-olefins by oxidatively intercepting Heck intermediates. Depending on the nature of the oxidant and the reaction conditions, these transformati

- Polyfunctionalized N-Tensides. VII. Substitution and Elimination in the Reaction of 1,2-Dihalogenoalkanes with Amines
-
1,2-Dichloroalkanes, 1,2-Dibromoalkanes and mixtures of 1-bromo-2-chloroalkanes and 1-chloro-2-bromoalkanes react with primary or secondary amines and give both elimination and substitution products, often in a nearly 1:1 proportion.The elimination products are the cis and trans-1-halo-1-alkenes, the 2-halo-1-alkenes, the 1,3- and 2,4-dienes and the 1-alkenes.The main substitution products are the 1,2-bis-aminoalkanes.Physical dates, 1H-n.m.r.-spectra,surface tension values and CMC-dates are given.

- MECHANISM OF RADICAL TELOMERIZATION OF ETHYLENE WITH 1,1-DICHLOROETHANE
-
The mechanism of the radical telomerization of ethylene with 1,2-dichloroethane was investigated. 1,2-Dichloroethane reacts with telomeric alkyl radicals with cleavage both of the C - H bond and of the C - Cl bond, and the ratio of the corresponding rate constants is 2.8 (100 deg C).It was shown that, in addition to the chlorine-containing telomers, the mixture of products from the reaction initiated by benzoyl peroxide contains alkyl- and dialkylbenzenes.
