Soc. 1958, 80 (8), 1953–1955.. Blomquist, Burge and Sucsy 2 have called attention to the fact that while with the cyclodecenes, the cis isomer has the higher … Cyclooctane is a cycloalkane with the molecular formula (CH2)8. It is a simple colourless hydrocarbon, but it is often a reference compound for saturated eight-membered ring compounds in general. Cyclooctane has a camphoraceous odor. Meer weergeven The conformation of cyclooctane has been studied extensively using computational methods. Hendrickson noted that "cyclooctane is unquestionably the conformationally most complex cycloalkane … Meer weergeven The main route to cyclooctane derivatives involves the dimerization of butadiene, catalysed by nickel(0) complexes such as nickel bis(cyclooctadiene). This process affords, among other products, 1,5-cyclooctadiene (COD), which can be hydrogenated. … Meer weergeven
Web9 sep. 2024 · An additional trans-cyclobutane fused at the 5,6-position of the cyclooctene reduces the ring strain energy of cyclooctene, enabling the corresponding polymers to depolymerize into the cis-cyclooctene monomers. The use of excess triphenylphosphine was found to be essential to suppress secondary metathesis and depolymerization. http://www.columbia.edu/itc/chemistry/c3045/client_edit/ppt/PDF/11_18_22.pdf
