Abstract

Reactions of α,β-conjugated enone compounds, and 2-diazo-5,5-dimethyl-1,3-hexanedione were carried out under the dirhodium tetraacetate (Rh2(OAc)4) catalyst. The structures of the obtained products were characterized by FT-IR, GC-MS, 1H NMR, and 13C NMR methods. 6,6-Dimethyl-3,5,6,7-tetrahydro-4H-spiro[benzofuran-2,2'-bicyclo[2.2.1]heptane]-3',4-dione was obtained from the reaction of 3-methylidene-bicyclo[2.2.1]heptan-2-one, the first α,β-conjugated enone compound used in the study, as a single product. The second α,β-conjugated enone compound, 1-morpholinoprop-2-en-1-one, did not react with Rh-carbene, and only the carbene dimer was obtained from this reaction.

Abstract

α,β-Konjuge enon bileşikleri ile 2-diazo-5,5-dimetil-1,3-heksandionun dirodyum tetraasetat (Rh2(OAc)4) katalizörlüğünde tepkimeleri gerçekleştirilmiştir. Elde edilen ürünlerin yapıları FT-IR, GC-MS ve 1H NMR ve 13C NMR yöntemleri ile karakterize edilmiştir. Çalışmada kullanılan ilk α,β-konjuge enon bileşiği olan 3-metiliden-bisiklo[2.2.1]heptan-2-onun tepkimesinden 6,6-dimetil-3,5,6,7-tetrahidro-4H-spiro[benzofuran-2,2’-bisiklo[2.2.1]heptan]-3’,4-dion bileşiği tek ürün olarak elde edilmiştir. İkinci α,β-konjuge enon bileşiği olan 1-morfolinoprop-2-en-1-on Rh-karbeni ile tepkime vermemiş olup bu tepkimeden sadece karben dimeri elde edilmiştir.
