Palladium catalysed oligomerization of 1-alkynes
The oligomerization of 1-pentyne using palladium acetyl acetonate catalyst with various solvents and ligands was investigated. An equimolar mixture of HOAc and Et N proved to be a superior solvent. The major product observed in most cases was the dimer, 6-methylene-nona-yne, although both cis and …

Cyanate Formation Following 2-Chloroacrylonitrile Exposure and the Role of Cytochrome P-450
… 2-CAN. Group 3 received 100 mg/kg of 5-phenyl-1-pentyne (5P1P) an inhibitor of cytochrome P-450. Group 4 received 100 mg/kg of 5P1P one hour before 40 mg/kg of 2-CAN. Three hours following administration, the animals were euthanized via cardiac puncture. Cardiac blood was collected for cyanide …

Role of adsorption in catalysis: applications of NMR relaxometry
… described with IR spectroscopy. For example, 1-pentyne showed the strongest interaction with the alumina (94 kJ mol-1) while 1-pentene presented a weaker interaction (46 kJ mol-1) on θ-Al2O3. Desorption energies obtained from TPD ranged 85 – 130 kJ mol-1, irrespective of the adsorbate. …
