The chemistry of selenophene
- 73 Downloads
In the present work it has been shown that 3-(2-selenenoylacetyl)-selenophene is enolized at the carboxyl group adjacent to the 2-selenienyl radical and 3-(benzoylacetyl)selenophene at the carboxyl group adjacent to the phenyl radical (judging from the formation of the corresponding isoxazoles by the reaction of these diketones with hydroxylamine). On reduction with lithium aluminum hydride, methyl 3-selenophenecarboxylate has given 3-selenienylmethanol and the nitrile of the same acid has yielded 3-selenophenealdehyde. Several new chalcones and isoxazoles with β-selenienyl radicals have been described.
