An efficient and highly atom-economical tandem Pd/Au-catalyzed route to α-sulfenylated carbonyl compounds from terminal propargylic alcohols and thiols has been developed. This one-step procedure has a wide substrate scope with respect to substituents at
Use of phenylselenium trichloride for simple and rapid preparation of α-phenylselanyl aldehydes and ketones
Houllemare, Didier,Ponthieux, Sylvain,Outurquin, Francis,Paulmier, Claude
, p. 101 - 106 (2007/10/03)
α-Phenylselanyl aldehydes are prepared on a large scale by reaction of PhSeCl3 with the corresponding aldehydes in acetonitrile without isolation of the intermediate dichloro adducts. This method has been applied to α-phenylselanyl ketones deri
Allylation and benzylation of enoltes derived from β-phenylselanyl silyl enol ethers

α-Phenylselanyl γ-unsaturated ketones were obtained through allylation of enolates generated by potassium t-butoxide cleavage of β-phenylselanyl silyl enol ethers derived from α-phenylselanyl ketones. With enoxysilanes prepared from α-phenylselanyl aldehydes, O-allylation and O-benzylation of the corresponding enolates were also observed.
Preparation of α,α-Bis(phenylseleno)ketones
Ponthieux, Sylvain,Outurquin, Francis,Paulmier, Claude
, p. 6453 - 6456 (2007/10/02)
α,α-Bis(phenylseleno)ketones have been synthesized by phenylselenenylation of enolates derived from α-phenylseleno ketones.Depending on the structure of the ketones, three experimental procedures were adopted.
Substitution Reactions of Thallous Thiophenoxide and Thallous Phenylselenide with Halogen-Bearing Substrates
Detty, Michael R.,Wood, Gary P.
, p. 80 - 89 (2007/10/02)
Thallous thiophenoxide (1) and thallous selenide (2) were prepared by the action of either thallous ethoxide or thallous pentoxide on thiophenol and benzeneselenol.The reagents 1 and 2 reacted readily with aroyl and acyl halides, imidoyl chlorides, α-halo ketones, α-halo esters, α-halo lactones, α-halo carboxylic acids, allyl halides, alkyl halides, chlorotrimethylsilane, chloroacetonitrile, and N-chlorosuccinimide to give substitution products and varying amounts of diphenyl disulfide and diphenyl diselenide.The reactions were run as heterogeneous mixtures in ether.The origin of the diphenyl disulfide and diphenyl diselenide was homolytic cleavage of the thallium-sulfur or thallium-selenium bond, on the basis of the products derived from the reactions of N-chlorosuccinimide with 1 and 2.
