[reaction: see text] beta-Methylselenenyl alpha,beta-unsaturatedketones were effectively synthesized by treating selenoamides with methyl triflate, followed by reaction with lithium acetylides. The reaction proceeded with high stereoselectivity to give exclusively Z-isomers. (77)Se NMR studies and X-ray molecular structure analysis of beta-methylselenenyl alpha,beta-unsaturatedketones suggested that
A new type of phosphorus-selenium containing heterocyclic compound, 3,4,5-tris(2,4-di-t-butyl-6-methoxyphenyl)-3,4,5-triselenoxo-1,2-diselena-3,4,5-triphospholane, was prepared and was allowed to react with amides to give the corresponding selenoamides in good yields.

The structure of a new type of phosphorus-selenium containing eight-membered heterocyclic compound, 1,2,3,5,7-pentaselena-4,6,8-triphosphocane, was unambiguously determined by the X-ray analysis as the revised structure for the 3,4,5-triselenoxo-1,2-diselena-3,4,5-triphospholane, which had been previously proposed as a selenation reagent of amides to selenoamides.
