Electrochemical selenium–π–acid promoted hydration of alkynyl phosphonates

Chemical Communications, Год журнала: 2022, Номер 58(54), С. 7566 - 7569

Опубликована: Янв. 1, 2022

An unprecedented electrochemical selenium-π-acid promoted hydration of internal alkynes bearing a phosphonate auxiliary was described. Thus, valuable (hetero)aryl and alkyl ketones could be accessed under mild, metal- external oxidant-free conditions. This protocol features high atom-economy, good chemo- regio-selectivity, excellent functional group tolerance easily transformable products. Control experiments demonstrate that assistance is essential for this transformation.

Iron-Promoted Catalytic Activity of Selenium Endowing the Aerobic Oxidative Cracking Reaction of Alkenes

Organic Letters, Год журнала: 2023, Номер 25(36), С. 6720 - 6724

Опубликована: Сен. 7, 2023

Oxidative cracking of alkenes is a significant process in industry. In this work, it was found that catalyzed by Se/Fe via hybrid mechanisms, the carbon–carbon double bond can break to produce carbonyls under mild conditions. Since O2 be used as partial oxidant, employed H2O2 amount reduced (90 mol % vs 250 %) avoid peroxide residues, making even safer for operation.
