Selenium Transfer from Secondary Phosphine Selenides to Aminoacetylenic Ketones: Access to 1,2-Dihydro‑3H‑pyrrole-3-selones with a Stable CSe Bond

Selenium Transfer from Secondary Phosphine Selenides to Aminoacetylenic Ketones: Access to 1,2-Dihydro‑3H‑pyrrole-3-selones with a Stable CSe Bond

Secondary phosphine selenides were found to react with γ-aminoacetylenic ketones (80–85 °C, MeCN, 17–40 h) to afford 1,2-dihydro-3H-pyrrole-3-selones in 48–80% yields, products of unprecedented selenium transfer from the PSe bond to replace the carbonyl oxygen and to form dihydro-3H-pyrrole-3-selon...

Zusammenfassung:Secondary phosphine selenides were found to react with γ-aminoacetylenic ketones (80–85 °C, MeCN, 17–40 h) to afford 1,2-dihydro-3H-pyrrole-3-selones in 48–80% yields, products of unprecedented selenium transfer from the PSe bond to replace the carbonyl oxygen and to form dihydro-3H-pyrrole-3-selones having a CSe bond stable under ambient conditions.
