Palladium-catalyzed formation of 3,5-diaryl-1,2,4-selenadiazoles from arylselenocarboxamide

A number of new and known arylselenocarboxamides (i.e. Ar-C(=Se)NH2; Ar=C6H5 (1), 4-BrC6H4 (2), 2-MeOC6H4 (3), 4-MeOC6H4 (4), 4-MeSC6H4/sub

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.

A synthetic and structural study of arylselenoamides and 2,4-diaryl-1,3- selenazoles

The systematic preparation of 2,4-diaryl-1,3-selenazoles was carried out by two-component cyclization of the primary selenoamides with α-halo ketones. Selenoamides were obtained from the reaction of Woollins' reagent with arylnitrile, followed by hydrolys

Synthesis, characterization and antibacterial activity of some new ferrocenyl selenazoles and 3,5-diferrocenyl-1,2,4-selenadiazole

New ferrocenyl containing selenazole derivatives were synthesized from reactions of aryl selenocarboxamide (i.e. Ar-CSe(NH2); ArC6H5 (1), 4-Br-C6H4 (2), 4-PhC6H4 (3), 4-CH3

Synthesis and antitumor-evaluation of 1,3-selenazole-containing 1,3,4-thiadiazole derivatives

A series of novel 1,3-selenazole-containing 1,3,4-thiadiazole derivatives bearing Schiff base moieties were synthesized and evaluated for their in vitro antiproliferative activities against human breast cancer cell MCF-7 and mouse lymphocyte leukemia cell

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.

Synthesis of 1,3-selenazoles and bis(selenazoles) from primary selenocarboxylic amides and selenourea

The reaction of nitriles with P2Se5 in the presence of EtOH-H2O afforded primary selenocarboxylic amides. The cyclization of these compounds with α-halo ketones afforded a variety of functionalized 1,3-selenazoles. The use of P2Se5 also allowed the convenient synthesis of selenocarboxylic diamides which were transformed into bis(selenazol-2-yl)alkanes ('bis-selenazoles'). A practical method for the synthesis of selenourea was developed. This useful small building block was successfully applied to the synthesis of primary 2-amino-1,3- selenazoles.

Efficient synthesis of primary selenocarboxylic amides by reaction of nitriles with phosphorous(V) selenide

The reaction of nitriles with P2Se5 in the presence of EtOH/H2O afforded a variety of primary selenocarboxylic amides.

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 convenient synthesis of selenocarboxamides from nitriles

Aromatic and aliphatic nitriles can be conveniently converted into the corresponding selenocarboxamides with monoselenophosphate in aqueous alcohol in 50-94% yield.
