| 1928 Burton & Ingold in Jrnl. Chem. Soc. i. 904 It can be seen in a general way that opposite conditions will prevail in mobile-anion tautomerism (anionotropy). Ibid. 905 The effect of groups in promoting anionotropic change. 1941 Trans. Faraday Soc. XXXVII. 721 (heading) Mechanism and Kinetics of Anionotropic Change. 1942 Nature 31 Jan. 128/2 Anionotropic change is, in some respects, similar to prototropic change... In anionotropy we are concerned with the movement of negative groups, and there is evidence that the interconversion may proceed through the intermediate formation of a positive mesomeric ion and a complementary negative ion. |
