Photoinduced electron transfer reactions of anthracene in CF3SO3H- CF3CO2H

Photolysis of anthracene in a mixture consisting of 2% CF3SO3H in CF3CO2H (w/w), where anthracene is partially protonated, gives a mixture of oxidized, neutral and reduced monomeric and dimeric products, initiation of this chemistry being photoinduced electron transfer from anthracene to protonated anthracene.

Studies on photodimerization of 9-anthracenecarboxylic acid in its crystalline double salt with diamine

With the intention of obtaining uncommon head-to-head anthracene dimers, double salts of 9-anthracenecarboxylic acid (9-AC) with several diamines were photolyzed in the solid state. 9-AC underwent decarboxylation and reduction as well as dimerization. Although the head-to-tail dimer and an unsymmetrical dimer were obtained, the head-to-head one was not produced.

Photolysis of 2,3:5,6-Dibenzo-7,7,8,8-tetraisopropyl-7,8-disilabicycloocta-2,5-diene: Evidence for Cyclodimerization of a Disilene

Evidence for disilene dimerization was obtained by generating tetraisopropyldisilene from the title compound via the photochemical retrodiene process which produced the expected dimerization product, octaisopropylcyclotetrasilane (30percent), in addition to the H-abstraction product, 1,1,2,2-tetraisopropyldisilane (5percent).
