Facile synthesis of selenocarboxamides from nitriles using Se/CO/H 2O under atmospheric pressure

Aromatic and aliphatic nitriles can be conveniently converted into the corresponding selenocarboxamides with Se/CO/H2O under atmospheric pressure without use of a base.

Synthesis of primary arylselenoamides by reaction of aryl nitriles with Woollins' reagent

The reaction of aryl nitriles with Woollins' reagent followed by water affords a variety of primary arylselenoamides In 60-100% yield. The first crystal structures of two primary selenoamides are reported.

Generation of 1,3-chalcogenaza-1,3-butadienes by thermal cycloreversion of 2,4,6-trisubstituted 6H-1,3,5-oxachalcogenazines

1,3-Thiaza- and 1,3-selenaza- 1,3-butadienes bearing several substituents at the C-2 and C-4 positions were generated through thermal cycloreversion of 6H-1,3,5-oxathiazines or 6H-1,3,5-oxaselenazines, respectively, and the heterodienes were efficiently trapped by using acetylenic dienophiles. When 6H-1,3,5-oxathiazines or 6H-1,3,5-oxaselenazines were heated in the presence of nucleophiles, such as alcohols or thiols, the corresponding 1,4-adducts of the heterodienes with the nucleophiles were obtained in good yields. On the other hand, heating of 6H-1,3,5-oxathiazines or 6H-1,3,5-oxaselenazines in the absence of trapping agents afforded several products which originated from the in situ generated 1,3-chalcogenaza-1,3-butadienes; also the heterodienes were not isolated or observed directly as the monomeric forms at all.

A facile preparation of aliphatic and aromatic primary selenoamides using 4-methylselenobenzoate as a new selenating reagent

Aliphatic and aromatic primary selenoamides 2 were isolated by the reaction of the corresponding aliphatic and aromatic nitriles with potassium 4-methylselenobenzoate in the presence of BF3·Et2O in moderate from high yields.

Convenient synthesis of primary selenoamides from aryl nitriles, selenium and sodium borohydride

Aryl nitriles react smoothly with sodium hydrogen selenide, itself prepared in situ from selenium and sodium borohydride, in ethanol to give the corresponding primary selenoamides in moderate to good yield.

Synthesis of primary selenocarboxamides and conversion of alkyl selenocarboxamides into selenazoles

Nitriles react with sodium hydrogen selenide, pyridine and hydrochloric acid in ethanol to give primary aryl and alkyl selenocarboxamides. The alkyl selenocarboxamides are converted into selenazoles by reaction with phenacyl bromide.

A Novel Synthesis of Primary Selenoamides from Nitriles by the Treatment of Bis(trimethylsilyl) Selenide and BF3*OEt2

Reaction of nitriles with (Me3Si)2Se in the presence of BF3*OEt2 afforded the corresponding primary selenoamides in moderate yields.A selenourea and a selenothiocarbamate were also prepared in a similar manner from the corresponding cyanamide and thiocyanate.

Electrochemical Preparation of Organic Diselenides

By the method of electrosynthesis a number of organic diselenides can be prepared simply and without danger.The cathodic polarisation of a special selenium electrode in aprotic solutions gives rise to polyselenideanions, which react with electrophilic compounds to the corresponding diselenides of the general formula RSeSeR (2a-e) with R = benzyl, 2-nitrophenyl, cyclohexyl, isopropyl, 4-cyanophenyl.
