New cyclic selenide. Synthesis, characterization and reactions of 2-methylselenolan
摘要:
Treatment of 1,4-dibromopentane with sodium selenide gave 2-methylselenolan (1), C5H10Se, as a yellow oil with an obnoxious odour. New derivatives of compound 1 (C5H10Se(R)X: R = X = I; R = X = Br; R = X = Cl; R = CH3, X = I; R = CH3, X = BPh4; R = C6H5, X = BPh4) have been prepared; H-1 NMR studies show the presence of cis/trans geometrical isomers.
