Preparation and catalytic properties of the triphenylarsine and triphenylstibine-stabilized tri-heteroleptic NHCPd‒allyl complexes

Publication date: Available online 17 January 2019Source: Journal of Organometallic ChemistryAuthor(s): Jin YangAbstractA series of triphenylarsine and triphenylstibine-stabilized tri-heteroleptic NHCPd‒allyl complexes were synthesized and characterized. The solid-state structures of the complexes shown mononuclear carbene palladium complexes, in which, each palladium centre was coordinated by an N-heterocyclic carbene, the η3-coordinated allyl moiety and an As or Sb donor. Further investigation of the Pd complexes as catalysts in Sonogashira coupling reaction was carried out and the obtained complexes exhibited good reactivities for aryl bromides.Graphical abstractThe graphical abstract synopsis: A series of triphenylarsine and triphenylstibine-stabilized tri-heteroleptic NHCPd‒allyl complexes were synthesized and used in Sonogashira coupling reaction.
