1,3,5,7-Cyclooctatetraene (COT) is an unsaturated derivative of cyclooctane, with the formula C8H8. It is also known as [8]annulene. This polyunsaturated hydrocarbon is a colorless to light yellow flammable liquid at room temperature. Because of its stoichiometric relationship to benzene, COT has … See more 1,3,5,7-Cyclooctatetraene was initially synthesized by Richard Willstätter in Munich in 1905 using pseudopelletierine as the starting material and the Hofmann elimination as the key transformation: Willstätter noted … See more Richard Willstätter's original synthesis (4 consecutive elimination reactions on a cyclooctane framework) gives relatively low yields. Reppe's synthesis of cyclooctatetraene, … See more The π bonds in COT react as usual for olefins, rather than as aromatic ring systems. Mono- and polyepoxides can be generated by reaction of COT with peroxy acids or … See more • Barrelene, structural isomer of cyclooctatetraene • Benzene • Cyclobutadiene See more Early studies demonstrated that COT did not display the chemistry of an aromatic compound. Then, early electron diffraction experiments concluded that the C-C bond distances were identical. However, X-ray diffraction data from H. S. Kaufman demonstrated … See more Cyclooctatetraene has been isolated from certain fungi. See more COT readily reacts with potassium metal to form the salt K2COT, which contains the dianion C 8H 8. The dianion is planar, octagonal, and See more WebThe angle sum trigonometric formula in cotangent function is written in several forms but it is popularly expressed in the following three forms.

Dividing through by c2 gives. a2 c2 + b2 c2 = c2 c2. This can be simplified to: ( a c )2 + ( b c )2 = 1.
