Sheng, Shou-Ri,Sun, Wu-Kang,Hu, Ming-Gang,Liu, Xiao-Ling,Wang, Qiu-Ying
, p. 97 - 99 (2008/02/05)
Vinyl phosphonates were prepared with good yields in a one-pot, two-step transformation by Mitsunobu reaction of 2-hydroxyalkyl phenyl selenides with monoethyl esters of phosphonic acid followed by oxidation-elimination.

Movassagh, Barahman,Shamsipoor, Mojgan
, p. 1316 - 1318 (2007/10/03)
Two convenient rapid, efficient, stereoselective and highly regioselective methods for the synthesis of β-hydroxy selenides by the direct opening of epoxides with diselenides in acetonitrile in the presence of either Zn/AlCl 3 or zinc powder in
Construction of tetrahydrofuran-3-ones from readily available organochalcogen precursors via radical carbonylation/reductive cyclization

, p. 3 - 6 (2007/10/03)
(matrix presented) β-Hydroxyalkyl aryl chalcogenides, readily available by regioselective ring-opening of epoxides with nucleophilic benzeneselenolate or tellurolate, were O-alkylated by treatment with ethyl propiolate or (E)-1,2-bis(phenylsulfonyl)ethyle

Duan, Aldehydesf De-Hui,Huang, Xian
, p. 26 - 27 (2007/10/03)
a-Arylseleno-substituted zinc and copper organometallics, in the presence of a Lewis acid, can react with aldehydes, ketones and enals with high chemoselectivity and_regioselectivity.
Formation of Some Oxygen-Containing Heterocycles by Radical Cyclization: The Stereochemical Influence of Anomeric Effects
Beckwith, Athelstan L. J.,Page, Dennis M.
, p. 5144 - 5153 (2007/10/03)
The influence of the anomeric effect on radical cyclization has been examined by determining the stereochemical outcome of the ring closure of 10 suitably substituted radicals. The stereochemistry of the products formed from the acyclic precursors 4a-f indicates that for suitably constituted radicals anomeric interactions stabilize pseudoaxially substituted transition structures 14 thus affording products with stereochemistry the reverse of that normally observed.
ANODIC PHENYLSELENYLATION OF ASYMMETRIC OLEFINS
Latypova, V. Z.,Zhuikov, V. V.,Berestovitskaya, V. M.,Kargin, Yu. M.
, p. 1517 - 1519 (2007/10/02)
The anodic phenylselenylation of asymmetric olefins is accompanied by vicinal addition of the active nucleophilic components (water, acetonitrile) at most substituted carbon atoms of the multiple bond.
PHENYLSELENENYL CHLORIDE IN ACETONITRILE-WATER; A HIGHLY CONVENIENT REAGENT FOR HYDROXYSELENATION OF OLEFINS AND PREPARATION OF CYCLIC ETHERS FROM DIENES
Toshimitsu, Akio,Aoai, Toshiaki,Owada, Hiroto,Uemura, Sakae,Okano, Masaya
, p. 5301 - 5306 (2007/10/02)
The reaction of phenylselenenyl chloride with olefins in aqueous acetonitrile affords β-hydroxyalkyl phenyl selenides in excellent yields, providing the most convenient method for hydroxyselenation of olefins so far reported.When the reaction was applied to conjugated dienes, monohydroxyselenated products were obtained in good to excellent yields.From non-conjugated dienes, on the other hand, cyclic ethers containing two phenylseleno groups were produced in good to excellent yields, the first step of this reaction being the hydroxyselenation of one double bond.
SYNTHESIS OF CONJUGATED NITROALKENES VIA NITROSELENENYLATION OF ALKENES
Hayama, Takashi,Tomoda, Shuji,Takeuchi, Yoshito,Nomura, Yujiro
, p. 4733 - 4734 (2007/10/02)
Addition of silver nitrite to 2-bromoalkyl phenyl selenide in the presence of mercury(II)chloride afforded 2-nitroalkyl phenyl selenide, wich upon oxidative deselenenylation provided the conjugated nitroalkene in excellent yield.
