Electrocyclic reactions. Part III. Some reactions of 2,4-dimethyl-1,5-diphenylpenta-1,4-dien-3-one (αα′-dimethyldibenzylideneacetone)

Autor: Charles W. Shoppee, Burgess J. A. Cooke

Publikováno v: J. Chem. Soc., Perkin Trans. 1. :1026-1030

αα′-Dimethyldibenzylideneacetone (I) by treatment with hot hydrochloric acid givestrans-2,5-dimethyl-3,4-diphenylcyclopent-2-enone (Va). With hot hydriodic acid the minor product is the cyclopentenone (Va) and the major product is trans-2,5-dimet

Electrocyclic reactions. Part IV. Some reactions of 2,4-dibromo-1,5-diphenylpenta-1,4-dien-3-one (αα′-dibromodibenzylideneacetone)

Autor: Charles W. Shoppee, Burgess J. A. Cooke

Publikováno v: J. Chem. Soc., Perkin Trans. 1. :2197-2202

Treatment of αα′-dibromodibenzylideneacetone (I) with hot hydriodic acid and red phosphorus has been claimed to yield 60% of cis-1,2-diphenylcyclopentane; in fact, the product consists of trans-3,4-diphenylcyclopentanone (24%), which is not reduc
