Abstract
AbstractThe investigation of electron transfer and subsequent reactions of divinylidene compounds not capable of anionic homopolymerization was extended to 1,3‐bis(1‐phenylvinyl)benzene (2). A new method for the preparation of this compound is described. Its reaction with Li, Na, and K as electron transfer reagents in THF as solvent results in an increasing yield in polymeric combination products of the radical anions formed primarily with increasing reducing power of the alkali metal.The main product, however, in any case is the cyclic dimeric tetra‐anion of 2, which upon protonation yields 1,4,11,14‐tetraphenyl[4.4]metacyclophane (3).
