prismane, n. Chem.|ˈprɪzmeɪn| [f. prism n. + -ane.] Any saturated hydrocarbon whose molecule contains six carbon atoms linked together in the shape of a triangular prism; spec. the isomer of benzene, C6H6 , which has this structure.
1964Tetrahedron Lett. May 1418 Prismane or ‘Ladenburg benzene’ ( C6H 6), which has local Cs symmetry, should have a JC-H of about 180 c.p.s. 1967New Scientist 26 Jan. 220/1 The first pure and properly characterized derivative of ‘prismane’, as it is called, has been synthesized. 1972DePuy & Chapman Molec. Reactions & Photochem. iv. 64 In this system a photostationary state..is established which involves a benzvalene derivative, a prismane derivative, and a Dewar benzene derivative, as well as the two tri-t-butylbenzenes. 1983McQuillin & Baird Alicyclic Chem. (ed. 2) viii. 191 It is therefore easy to understand the thermal stability of prismanes. |
