Reaction of diisobutylaluminium hydride with selenium and tellurium: New reagents for the synthesis of seleno- and telluro-amides
Li, Guang Ming,Zingaro, Ralph A.
, p. 647 - 650 (1998)
Diisobutylaluminium hydride (BuI2AlH) undergoes reaction with elemental selenium and tellurium to afford new reagents having an Al-Se or an Al-Te bond. These directly convert amides to selenoamides and telluroformamides. This affords
Selenocarbonyl synthesis using Woollins reagent
Bhattacharyya, Pravat,Woollins
, p. 5949 - 5951 (2001)
[PhP(Se)(μ-Se)]2 selenates secondary and tertiary amides to the corresponding selenoamides in 30-70% yields at 130°C in toluene and indolizine-3-aldehydes to selenoaldehydes in 40-59% yield at 25°C.

, p. 199 - 200 (1995)
A new type of phosphorus-selenium containing heterocyclic compound, 3,4,5-tris(2,4-di-t-butyl-6-methoxyphenyl)-3,4,5-triseleno-1,2-diselena-3,4,5-triphospholane, was prepared and was allowed to react with amides to give the corresponding selenoamides in g
Copper(0)-induced aminocyclopropanation of olefins via deselenation of N,N-disubstituted aromatic selenoamides
Mitamura, Takenori,Nomoto, Akihiro,Sonoda, Motohiro,Ogawa, Akiya
experimental part, p. 9983 - 9988 (2009/04/03)
Upon heating of a mixture of N,N-disubstituted aromatic selenoamides and several electron-deficient olefins in the presence of copper(0) powder, a novel deselenative cyclopropanation takes place to afford the corresponding aminocyclopropanes in good yields. When acrylonitrile is employed as an electron-deficient olefin, the aminocyclopentanation occurs in preference to the aminocyclopropanation by prolonging the reaction time. The obtained aminocyclopropane derivatives can be converted to the corresponding 1,4-dicarbonyl compounds upon treatment with 2 N HCl.
Tertiary selenoamide compounds are useful superoxide radical scavengers in vitro
Takahashi, Hitoe,Nishina, Atsuyoshi,Kimura, Hirokazu,Motoki, Kenji,Koketsu, Mamoru,Ishihara, Hideharu
, p. 207 - 211 (2007/10/03)
We investigated the scavenging effects of tertiary selenoamide compounds for super oxide radicals using a highly sensitive and quantitative chemiluminescence method. At 333 nM, tertiary selenoamide compounds scavenged 25.8-81.6% of O2-/su
Facile conversion of amides and lactams to selenoamides and selenolactams using tetraethylammonium tetraselenotungstate
Saravanan, Vadivelu,Mukherjee, Chandan,Das, Saibal,Chandrasekaran, Srinivasan
, p. 681 - 683 (2007/10/03)
Chloroiminium salts generated in situ from amides and lactams using (COCl)2 or POCl3 react very readily with the new selenium transfer reagent, tetraethylammonium tetraselenotungstate, (Et 4N)2WSe4, 1
Facile synthesis of N,N-dialkylselenoamides from amides
Koketsu, Mamoru,Okayama, Yoshihiro,Aoki, Hiroshi,Ishihara, Hideharu
, p. 195 - 198 (2007/10/03)
The synthesis of the N,N-dialkylselenoamides from amides was discussed. These selenoamides were chlorinated with oxalyl chloride and then they were allowed to react with LiAlHSeH to afford the corresponding N,N-dialkylamides in moderate to good yields. Af
1,2,3,5,7-pentaselena-4,6,8-triphosphocane as the revised structure for "3,4,5-triselenoxo-1,2-diselena-3,4,5-triphospholane" determined by X-ray analysis
Yoshifuji, Masaaki,Higeta, Naru,An, De-Lie,Toyota, Kozo
, p. 17 - 18 (2007/10/03)
The structure of a new type of phosphorus-selenium containing eight-membered heterocyclic compound, 1,2,3,5,7-pentaselena-4,6,8-triphosphocane, was unambiguously determined by the X-ray analysis as the revised structure for the 3,4,5-triselenoxo-1,2-disel
The invention of radical reactions. Part XXXVII. A convenient radical synthesis of dialkyl diselenides from carboxylic acids
Barton, Derek H. R.,Fontana, Giovanni
, p. 11163 - 11176 (2007/10/03)
A new and convenient synthesis of dialkyl diselenides from carboxylic acids by Barton PTOC ester based radical chemistry is described. This method was especially successful when O-cholestan-3β-yl-2,2,2-trichloroselenoacetate and O-neopentyl selenobenzoate
Conversion of Amides, N,N,N',N'-Tetramethylurea, and Esters to the Corresponding Selenoxo Compounds by Treatment with Bis(trimethylsilyl) Selenide and BF3*OEt2

The reactions of amides and N,N,N',N'-tetramethylurea with (Me3Si)2Se in the presence of BF3*OEt2 afforded the corresponding selenoxo compounds in good yields.On the other hand, selenation of ethyl and butyl benzoates in a similar manner gave benzoin and 2,3,5,6-tetraphenyl-1,4-diselenin via selenoesters.The trapping of selenoesters was also achieved by 2,3-dimethyl-1,3-butadiene to afford cycloadducts.
