Abstract

The in-situ Grignard addition method adds intermediately prepared organo alkaline-earth metal halides onto a suitable substrate. Here, freshly rasped calcium and the carbodiimide R'─N═C═N─R' (R' = SiMe₃, iPr) are suspended in THF at room temperature and then an organyl halide R─X (X = Br, I) is added. Within several hours, intermediately formed R─Ca─X adds onto the carbodiimide yielding the corresponding thf adducts of the amidinato calcium halide {(R'N)₂C─R}CaX. Suitable organyl halides besides aryl iodide are methyl and ethyl halide whereas bulkier isopropyl and tert-butyl iodides give very low yields.

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.
