Abstract
The reaction of selenium dihalides with pent-4-en-1-ol has been carried out for the first time. Efficient procedures for the synthesis of previously unknown bis(tetrahydrofuran-2-ylmethyl) selenide, dihalobis( tetrahydrofuran-2-ylmethyl)-λ4-selanes, and bis(tetrahydrofuran-2-ylmethyl) selenoxide have been developed on the basis of this reaction. The product structures have been studied by 1H, 13C, and 77Se NMR. Bis(tetrahydrofuran-2-ylmethyl) selenide and dihalobis(tetrahydrofuran-2-ylmethyl)-λ4-selanes represent equimolar mixtures of two diastereoisomers which display different signals in the 13C and 77Se NMR spectra. The oxidation of bis(tetrahydrofuran-2-ylmethyl) selenide with sodium periodate in methanol leads to the corresponding selenoxide consisting of 4 diastereoisomers.
