Correlation of Alkyl and Polar Groups in the Gas-Phase Pyrolysis Kinetics of α-Substituted Ethyl Chlorides

The kinetics of the gas-phase pyrolysis of several secondary chlorides were determined in a static system over the temperature range 369.9-490.1 deg C and the pressure range of 28-298 Torr.The reactions in seasoned vessels, with the free radical suppressor propene and/or toluene always present, are homogeneous and unimolecular and obey a first-order rate law.The observed rate coefficients are represented by the following Arrhenius equations: for 2-chloropropionitrile, log k1 (s-1) = (13.45+/-0.57)-(236.1+/-8.2) kJ mol-1; for methyl 2-chloropropionate, log k1 (s-1) = (12.22+/-0.54) - (217.0+/-7.4) kJ mol-1 (2.303RT)-1; for methyl 3-chlorobutyrate, log k-1 (s-1) = (13.65 +/-0.39)-(214.9+/-5.0) kJ mol-1 (2.303RT)-1.The data of this work together with those reported in the literature confirm previous correlations that α-alkyl substituents of ethyl chloride give a good straight line, when log k/k0 vs. ?* values (ρ* = -3.58 +/- 0.24, correlation coefficient = 0.996, and intercept = -0.0066 at 360 deg C) are plotted, while α-polar substituents give rise to an inflection point at ?*(CH3) = 0.00 into another straight line (ρ* = -0.46+/-0.06, correlation coefficient = 0.972, and intercept = 0.017 at 360 deg C).Several other polar α-substituents have been found to enhance the dehydrochlorination process by means of their electron delocalization or resonance effect.Revising a work reported on the pyrolysis kinetics of pinacolyl chloride, a Wagner-Meerwein rearrangement appears to be a reasonable explanation for the formation of about 12percent of the 2,3-dimethylbutene products.

Nickel-Catalyzed Alkyl-Alkyl Cross-Electrophile Coupling Reaction of 1,3-Dimesylates for the Synthesis of Alkylcyclopropanes

Cross-electrophile coupling reactions of two Csp3-X bonds remain challenging. Herein we report an intramolecular nickel-catalyzed cross-electrophile coupling reaction of 1,3-diol derivatives. Notably, this transformation is utilized to synthesize a range of mono- and 1,2-disubstituted alkylcyclopropanes, including those derived from terpenes, steroids, and aldol products. Additionally, enantioenriched cyclopropanes are synthesized from the products of proline-catalyzed and Evans aldol reactions. A procedure for direct transformation of 1,3-diols to cyclopropanes is also described. Calculations and experimental data are consistent with a nickel-catalyzed mechanism that begins with stereoablative oxidative addition at the secondary center.

Deoxygenation of Epoxides with Carbon Monoxide

The use of carbon monoxide as a direct reducing agent for the deoxygenation of terminal and internal epoxides to the respective olefins is presented. This reaction is homogeneously catalyzed by a carbonyl pincer-iridium(I) complex in combination with a Lewis acid co-catalyst to achieve a pre-activation of the epoxide substrate, as well as the elimination of CO2 from a γ-2-iridabutyrolactone intermediate. Especially terminal alkyl epoxides react smoothly and without significant isomerization to the internal olefins under CO atmosphere in benzene or toluene at 80–120 °C. Detailed investigations reveal a substrate-dependent change in the mechanism for the epoxide C?O bond activation between an oxidative addition under retention of the configuration and an SN2 reaction that leads to an inversion of the configuration.
