, p. 1425 - 1431 (2007/10/02)
Cyclopropanes were obtained from electron deficient olefins and acid carbon compounds by oxidation by iodine in the presence of KF on alumina. The reaction allows the synthesis of cyclopropanediyldiphosphonates.
ALKYLATION OF CH ACIDS IN THE PRESENCE OF POTASSIUM CARBONATE. I. ALKYLATION OF CH ACIDS BY ETHYL α-BROMOACRYLATE AND ITS DERIVATIVES
Vardapetyan, A. A.,Khachatryan, D. S.,Panosyan, G. A.,Morlyan, N. M.
, p. 2030 - 2034 (2007/10/02)
In the reaction of malonic and acetoacetic esters, acetylacetone, dimedone, and acetophenone with ethyl α-bromoacrylate and its derivatives in the presence of potassium carbonate the ratio of the obtained cyclopropane and dihydrofuran derivatives depends mainly on the pKa values of the initial CH acids.
A New Synthetic Route to Electrophilic Cyclopropane Derivatives from Olefins
Kawabata, Nariyoshi,Yano, Shinji,Hashimoto, Jiro,Yoshida, Jun-ichi
, p. 2539 - 2540 (2007/10/02)
1,1-Bis(alkoxycarbonyl)-, 1-alkoxycarbonyl-1-cyano-, and 1,1-dicyanocyclopropane derivatives were obtained in 10-99percent yields by the reaction of Br2C(COOR)2, Br2C(CN)(COOR), and KBr4, respectively, with olefins and Cu2Br2 in dimethyl sulfox
