Silicon-mediated synthesis of selenoaldehydes and selenoacylsilanes and their hetero diels-alder reactions

Bis(trimethylsilyl)selenide (HMDSS) reacts efficiently with aldehydes in the presence of CoCl2.6H2O to afford selenoaldehydes, which are trapped as Diels-Alder adducts by different dienes. The reaction can be applied to acylsilanes, to afford selenoacylsilanes, isolated as their cycloadducts.

Stannic chloride-induced unsymmetrical C-se bond cleavage of bis(N,N-dimethylcarbamoylseleno)methanes: Novel generation of selenoaldehydes

Treatment of bis(N,N-dimethylcarbamoylseleno)methanes with SnCl4 afforded β-1,3,5-triselenanes in moderate to high yields, and the key intermediates of the reactions, i.e., acylselonium ions and selenoaldehydes, were successfully trapped by usi

Generation of selenoaldehydes via retro Diels-Alder reaction and their behavior in the reaction with some enophiles

The [4 + 2] cycloadducts of selenoaldehydes and anthracene regenerate selenoaldehydes in situ quantitatively under neutral conditions via thermal retro Diels-Alder reaction. The reactions of selenoaldehydes generated by this method with 2-silyloxy-1,3-but

Novel generation of selenoaldehydes through stannic chloride-induced unsymmetrical C-Se bond cleavage of bis(N,N-dimethylcarbamoylseleno)methanes

Treatment of a benzene or a CH2Cl2 solution of bis(N,N-dimethylcarbamoylseleno)methanes with SnCl4 afforded β-1,3,5-triselenanes, and the key intermediates, acylselonium ions and selenoaldehydes, were successfully trapped

Efficient Synthesis of Selenocarbonyl Compounds by Treating Carbonyl Compounds with Bis(1,5-cyclooctanediylboryl) Selenide

Selenoaldehydes and selenoketones were generated in situ, by treating aldehydes or ketones, respectively, with bis(1,5-cyclooctanediylboryl) selenide; the resulting selenocarbonyl compounds were trapped with 2,3-dimethyl-1,3-butadiene to give the correspo

A Willgerodt-Kindler Type Selenation of Dihalomethane Derivatives, Chloroform, and Sodium Trichloroacetate by Treating with a Base, Elemental Selenium, and an Amine

Treatment of dihalomethane derivatives, chloroform, or sodium trichloroacetate with elemental selenium in the presence of NaH and an excess amount of an amine gave the corresponding selenoamides, selenoureas, and bis(selenocarbamoyl) triselenides in modest yields. These products were afforded from reactive intermediates related to "selenocarbonyl halides" and "selenophosgenoids" generated by the reaction of dichloromethanide ions and trichloromethanide ion with N-alkylated aminopolyselenide species (R2N-(Se)n-).

Convenient Syntheses of N,N-Dialkylselenoamides and N,N,N',N'-Tetraalkylselenoureas by Treating Terminal gem-Dihaloalkanes, Chloroform , or Sodium Trichloroacetate with a Base, Elemental Selenium, and Amines

Treatment of terminal gem-dihaloalkanes, chloroform or sodium trichloroacetate with elemental selenium in the presence of NaH and an excess amount of primary or secondary amines gave selenoamides and selenoureas in modest yields.

An efficient construction of a selenocarbonyl unit by the reaction of acetal derivatives with bis(dimethylaluminum) selenide

The construction of a carbon-selenium double bond was achieved by the reaction of acetal derivatives with bis(dimethylaluminum) selenide, and a variety of selenocarbonyl compounds containing selenoaldehydes, selenoformamides, and selenonesters were effici

An Efficient Synthesis of Selenocarbonyl Compounds by the Treatment of Carbonyl Compounds with Bis Selenide

An efficient synthesis of selenoaldehydes, selenoketones, and selenoamides was achieved by the treatment of carbonyl compounds with bis selenide.

The Reaction of Wittig Reagents with Selenium. Formation of Selenoaldehydes

The reaction of Wittig reagents with elemental selenium gave the corresponding selenoaldehydes which further reacted with other Wittig reagents to give the corresponding dimeric olefins in good yields.The selenoaldehydes formed afforded corresponding adducts by the reaction with dienes.These selenoaldehydes obtained by retro Diels-Alder reaction were also found to react with Wittig reagents to give the corresponding olefins in good yields.
