摘要

间terphenylhydridostannylene与β-二酮胺氧化镁和钙氢化物反应生成-μ - 2-氢化物，在加入THF供体溶剂后仍保持其杂双金属结构。在这两种情况下，与己-1-烯的反应都会生成四价有机锡基碱土衍生物。镁试剂经历了简单的两次加成，而钙中心过程在一次烯烃还原事件后被阻止。这种对比行为被认为是由于较重的碱土元素能够与间terphenyl配体的芳烃取代基形成持久的聚hapto相互作用。

Hydridostannylene Derivatives of Magnesium and Calcium

Reactions of a m-terphenylhydridostannylene with β-diketiminato magnesium and calcium hydrides provide bis-μ₂-hydrido species, the heterobimetallic constitutions of which are maintained after the addition of THF donor solvent. In both cases, reactions with hex-1-ene result in the formation of tetravalent organostannyl alkaline earth derivatives. Whereas the magnesium reagent undergoes facile twofold addition, the calcium-centered process is arrested after a single alkene reduction event. This contrasting behavior is assessed to result from the heavier alkaline earth element's ability to form a persistent polyhapto interaction with an arene substituent of the m-terphenyl ligand.

期刊介绍： Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields. Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world. All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times. The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems. Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
