Thermal Rearrangements, XX [1] The Kinetics of Thermal Isomerisation of 4‐Methyl‐1,2,5‐hexatriene in the Gas Phase
Autor: Gerhard Wachholz, Henning Hopf, Robin Walsh
Publikováno v: Chemische Berichte. 125:711-721
4-Methyl-1,2,5-hexatriene (13) has been prepared and subjected to gas-phase pyrolysis. Above 220°C, 13 rearranges reversibly to both trans-5-hepten-1-yne (14) and its cis-isomer 15. Formation of 14 is faster than that of 15. These isomerisations are

Thermal Rearrangements, XIX. The Kinetics of the Thermal Isomerization of 1‐Ethynyl‐2,2,3,3‐tetramethylcyclopropane
Autor: Henning Hopf, S. Teichmann, Armin de Meijere, Gerhard Wachholz, Robin Walsh
Publikováno v: Chemische Berichte. 122:377-382
1-Ethynyl-2,2,3,3-tetramethylcyclopropane (9) has been prepared and subjected to gas phase pyrolysis. Above 200°C the hydrocarbon rearranges to 4,4,5-trimethyl-1,2,5-hexatriene (10) and 5,6-dimethyl-5-hepten-1-yne (11). Whereas the allene is produce

Gas phase kinetics of pyrolysis of 1‐methyl‐1‐cyclopropene
Autor: Gerhard Wachholz, Robin Walsh, Henning Hopf
Publikováno v: Chemische Berichte. 118:3579-3587
The title study has been carried out in the temperature range 210 – 250°C. The isomerisation products are 2-butyne (91 – 94%), 1,3-butadiene (5 – 8%), and 1,2-butadiene (1 – 2%). No other products were detected and material recovery was comp

Gas-phase kinetics of pyrolysis of 1,2-dimethylcyclopropene
Autor: Henning Hopf, Gerhard Wachholz, Robin Walsh
Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :1103
The pyrolysis of 1,2-dimethylcyclopropene has been studied in the temperature range 260–300 °C. The sole product is isoprene and material recovery was complete to within ±3.5%. The reaction obeyed first-order kinetics and appeared to be homogeneo
