Light-induced carbocyclization of iodoalkenes
Campos-Gómez, Esther,Campos, Pedro J.,González, Héctor F.,Rodríguez, Miguel A.
experimental part, p. 4292 - 4295 (2012/07/16)
The direct irradiation of iodoalkenes leads to the formation of carbon-centered radical by homolysis of the C-I bond. The photoreaction is used in cyclizations with formation of six membered rings.
Synthesis of enantiopure 1,4-dioxanes, morpholines, and piperazines from the reaction of chiral 1,2-diols, amino alcohols, and diamines with vinyl selenones
Bagnoli, Luana,Scarponi, Catalina,Rossi, Maria Giovanna,Testaferri, Lorenzo,Tiecco, Marcello
scheme or table, p. 993 - 999 (2011/03/20)
The reactions of readily available vinyl selenones with enantiopure 1,2-diols, N-protected-1,2-aminoalcohols, and diamines gave substituted enantiopure 1,4-dioxanes, morpholines, and piperazines, respectively, in good to excellent yields. The same procedu
Preparation of the first bench-stable phenyl selenolate: An interesting "on water" nucleophilic reagent
Santi, Claudio,Santoro, Stefano,Battistelli, Benedetta,Testaferri, Lorenzo,Tiecco, Marcello
scheme or table, p. 5387 - 5390 (2009/05/07)
In this communication we report the synthesis and the characterization of the first solid and air-stable selenolates, starting from commercially available phenylselenenyl halides and elemental zinc. These reagents were efficiently employed in the ring ope
Synthesis of chalcogenides using indium intermediates in aqueous media
Galindo, Andréa C.,Oliveira, Juliana M.,Barboza, Maria A. G.,Gon?alves, Simone M. C.,Menezes, Paulo H.
, p. 129 - 140 (2007/10/03)
Selenides and vinylic selenides were synthesized from their corresponding organic halides and alkynes in aqueous media using indium metal.
A simplified preparation of vinyl sulfides, selenides and tellurides by a Wittig-type reaction
Silveira, Claudio C.,Begnini, Mauro L.,Boeck, Paula,Braga, Antonio L.
, p. 221 - 224 (2007/10/03)
The preparation of several vinyl sulfides, selenides and tellurides by Wittig-type reaction in a one-pot procedure is described. The chalcogenyl triphenylphosphoranes 3 are formed 'in situ' by the reaction of chloromethyl phenyl chalcogenide, potassium tert-butoxide and triphenylphosphine. Reaction of 3 with carbonyl compounds affords the vinyl chalcogenides 6-9 with preferential Z-configuration.
The first example of transitionmetal-catalyzed hydroselenation of acetylenes
Kuniyasu, Hitoshi,Ogawa, Akiya,Sato, Ken-Ichiro,Ryu, Iihyong,Sonoda, Noboru
, p. 5525 - 5528 (2007/10/02)
A variety of transition metal complexes catalyzed the regioselective hydroselenation of acetylenes. In particular, the palladium acetate-catalyzed reaction afforded the Markovnikov adducts with high selectivity.
A Direct Formation of Alkenyl Chalcogenides from Nonactivated Alkenyl Halides and Diorganyl Dichalcogenides under Neutral Conditions
Ogawa, Takuji,Hayami, Kazuo,Suzuki, Hitomi
, p. 769 - 772 (2007/10/02)
Alkenyl sulfides and selenides were easily obtained in moderate to good yields by heating the corresponding bromides with diorganyl disulfides or diselenides in hexamethylphosphoric triamide with or without copper(I) iodide as a promoter.
Et3B Induced Radical Addition of Thiols to Acetylenes
Ichinose, Yoshifumi,Wakamatsu, Kuni,Nozaki, Kyoko,Birbaum, Jean-Luc,Oshima,Koichiro,Utimoto, Kiitiro
, p. 1647 - 1650 (2007/10/02)
Thiols added easily to acetylenic compounds in the presence of Et3B to give alkenyl sulfides in good yields.The reaction of acetylenes with 3-methyl-2-buten-1-thiol gave dihydrothiophene derivatives in one pot.
