- 2-(pyrazol-4-yl)-1,3-oxaselenolanes from pyrazole carbaldehydes and 2-selanyl-1-ethanol
-
Pyrazole carbaldehydes react with 2-selanyl-1-ethanol at room temperature in the presence of trimethylchlorosilane followed by treatment C with triethyl amine to afford the corresponding 2-(pyrazol-4-yl)-1,3-oxaselenolanes. The structure of the novel compounds was confirmed by IR, 13 C, 1 H, 15N, and 77 Se NMR spectroscopy.this article online at wileyonlinelibrary.com.
