Synthesis, characterization and biological studies of organoselenium trans-palladium(II) complexes

Background: Over the years, transition metal complexes have exhibited significant antimicrobial and antitumor activity. It all started with cisplatin discovery, but due to the large number of side effects it shows, there is a growing need to find a new me

An efficient route to phenylselenoethers in the presence of Ag2O

An efficient protocol for the preparation of phenylselenoethers from unsaturated alcohols using phenylselenenyl halides at room temperature was developed. The procedure employs phenylselenenyl chloride and bromide, some Δ 4- and Δ 5-

Studies of the reactions of some benzenalkenyl ethers with benzenselenenyl halides

Intramolecular cyclization of some benzenalkenyl ethers with benzenselenenyl halides (PhSeX, X=Cl and Br) at different temperatures (- 78°C, 0°C and room temperature) has been investigated. It has been found that Δ4-alkenyl benzyl ethers. affor

Iodosobenzene diacetate and diphenyl diselenide: An electrophilic selenenylating agent of double bonds

Phenylseleno-acetoxylation, hydroxylation, etherification and lactonization products are obtained in good yields from the reaction of alkenes with diphenyl diselenide and iodosobenzene diacetate, in acetonitrile.

Oxidation of Diphenyl Diselenide with Ceric Ammonium Nitrate: a Novel Route for Functionalization of Olefins

Alkenes were reacted with diphenyl diselenide in presence of ceric ammonium nitrate in methanol, affording β-methoxyalkyl phenyl selenides in good yields.

Regioselectivity in Cyclofunctionalization of Olefinic Alcohols with Benzeneselenenyl Halides at Different Temperatures

The regioselectivity in cyclofunctionalization of some acyclic olefinic alcohols with benzeneselenenyl halides (PhSeCl and PhSeBr) at different temperatures (-78 deg C, 0 deg C and room temperature) is investigated.It has been found that Δ4- and Δ5-alkenols are converted into five- and/or six-membered cyclic phenyl selenoethers, the yield of which decreases with increasing temperature.PhSeCl has been found to be more efficient than PhSeBr in the cyclization reactions.

Electrochemical cyclization of unsaturated hydroxy compounds. Phenylselenoetherification and phenylselenolactonization

Phenylselenoetherification and phenylselenolactonization were performed in one step by electrolysis of unsaturated alcohols or carboxylic acids and diphenyl diselenide in organic solvent containing halide ions as mediators.

Ring-Closure Reactions Initiated by the Peroxydisulfate Ion Oxidation of Diphenyl Diselenide

The oxidation of diphenyl diselenide with ammonium peroxydisulfate proceeded cleanly to afford phenylselenium cations and sulfate anions.This is a very simple and efficient method to produce phenylselenium cations in the absence of nucleophilic counterions.This reaction was employed to effect selenium-induced ring closure reactions starting from alkenes containing internal nucleophiles.Thus, unsaturated alcohols and amides, β-diketones and β-keto esters gave the products of phenylselenoetherification.The same process occurred with dienes and unsaturated ketones when the reaction was carried out in the presence of water or methanol, respectively.Unsaturated acids, esters, and imides afforded the phenylselenolactonization products.

CYCLIZATION OF OLEFINIC ALCOHOL BY BENZENESELENENYL TRIFLATE

Cyclization of 4-, 5-, and 6-hydroxyalkenes with benzeneselenenyl triflate afforded corresponding tetrahydrofurans and -pyrans.

ELECTROCHEMICAL CYCLIZATION OF UNSATURATED HYDROXY COMPOUNDS. PART I. PHENYLSELENOETHERIFICATION

One-step cyclization of alkenols has been accomplished by electrooxidative phenylselenoetherification.The reaction was performed by electrolysis of unsaturated alcohols and diphenyl diselenide in methylene chloride containing tetraethylammonium bromide.
