Achieving pH and Qr Oscillations in a Palladium Catalysed Phenylacetylene Oxidative Carbonylation Reaction Using an Automated Reactor System
نویسندگان
چکیده
This letter reports an experimental study which achieves reproducible oscillations in both pH and heat output (Qr) during a palladium-catalysed phenylacetylene oxidative carbonylation reaction in an homogeneous catalytic system (PdI2-KI-Air-NaOAc in methanol solution). Experiments were performed in an HEL SIMULAR reaction calorimeter with precise control of temperature and gas flow rates. Under certain experimental conditions a second set of oscillations was observed.

The Effect of Temperature on Selectivity in the Oscillatory Mode of the Phenylacetylene Oxidative Carbonylation Reaction
Reaction temperature plays a major role in product selectivity in the oscillatory mode of the palladium-catalyzed phenylacetylene oxidative carbonylation reaction. At 40 °C, dimethyl (2Z)-2-phenyl-2-butenedioate is the major product whereas at 0 °C the major product is 5,5-dimethoxy-3-phenyl-2(5H)-furanone. The occurrence of oscillations in pH coincides with an increase in the rate of phenylace...
متن کاملOscillatory carbonylation using alkyne-functionalised poly(ethylene glycol).
In this study palladium-catalysed oscillatory carbonylation has been achieved using mono alkyne-terminated poly(ethylene glycol) methyl ether substrates. Reproducible, synchronised oscillations in pH and solution turbidity have been recorded over several days. A reaction network accounting for the observed phenomena has been proposed.
متن کاملHydroformylation of olefins and reductive carbonylation of aryl halides with syngas formed ex situ from dehydrogenative decarbonylation of hexane-1,6-diol.
A variety of primary alcohols have been investigated as convenient substrates for the ex situ delivery of carbon monoxide and molecular hydrogen in a two-chamber reactor. The gaseous mixture is liberated in one chamber by an iridium-catalysed dehydrogenative decarbonylation of the alcohol and then consumed in the other chamber in either a rhodium-catalysed hydroformylation of olefins or a palla...
متن کاملPalladium catalysed β-selective oxidative Heck reaction of an electron-rich olefin.
A palladium catalysed oxidative β-arylation of an electron-rich olefin is described. The reaction was under mild conditions; meanwhile, additives and directing groups are not needed. Various arylboronic acids worked well under the standard conditions.

2-Ynamides can be synthesised through PdII catalysed oxidative carbonylation, utilising low catalyst loadings. A variety of alkynes and amines can be used to afford 2-ynamides in high yields, whilst overcoming the drawbacks associated with previous oxidative methods, which rely on dangerous solvents and gas mixtures. The use of [NBu4 ]I allows the utilisation of the industrially recommended sol...
