Kinetics and mechanism of the dehydrohalogenation of Ar2CHCX3 and Ar2CHCHX2 by strong N-bases

The kinetics and mechanism of the elimination reactions of 1,1,1- trifluoro-, 1,1,1-trichloro-, 1,1,1-tribromo-, 1,1-dichloro- and 1,1-dibromo- 2,2-bis(4-nitrophenyl)ethanes and two strong N-bases: 1,5,7- triazabicyclo[4.4.0]dec-5-ene (TBD) and 7-methyl-1

KINETICS AND ISOTOPE EFFECTS OF THE β-ELIMINATION REACTIONS OF 1,1-DICHLORO-2,2-BIS-(4-NITROPHENYL)-ETHANE PROMOTED BY PIPERIDINE, PYRROLIDINE AND QUINUCLIDINE BASES IN ACETONITRILE SOLVENT

The kinetics of the reaction of 1,1-dichloro-2,2-bis-(4-nitrophenyl)ethane (I) with piperidine, pyrrolidine and quinuclidine bases in acetonitrile solvent are reported.The reaction is complex, leading to 1-amino-2,2-bis-(4-nitrophenyl)ethene (III) as the final product via the intermediate 1-chloro-2,2-bis-(4-nitrophenyl)ethene (II).The reaction shows a 100percent conversion of the substrate (I) to (II).The rate of reaction of I to II is several times faster than II to III, allowing for kinetic measurements of the initial step.The entropies of activation (ΔS*/J mol-1K-1) are negative and large (-184, -149, -145) for the reaction with piperidine, pyrrolidine and quinuclidine respectively.The free enthalpy of activation (ΔG*/kJ mol-1) are rather small, oscillating between 75-79 kJ mol-1.The kinetic isotope effects kH/kD fall between 6.8 and 7.6 at 20 deg C.The results obtained are interpreted in terms of E2H with a contribution of (E1cB)I mechanism.

KINETICS, ISOTOPE EFFECTS AND MECHANISM OF THE REACTION OF SOME DINITROPHENYLETHANES WITH SODIUM PROPANETHIOLATE IN PROPANOL

The reaction between Ar2CHCF3, Ar2CHCCl3, Ar2CHCHCl2 (where Ar=O2NC6H4) and sodium propanethiolate in propanol has been investigated.The reaction of Ar2CHCF3 with sodium propanethiolate gave the following alkenes: Ar2C=CF2, Ar2C=CF(SPr) and Ar2C=C(SPr)2,
