A series of new calix[4]arenes bearing one or two imidazoliums units in the lower rim were synthesized as precursors of N-heterocyclic carbenes for the synthesis of the corresponding nickel complexes. All products obtained were characterized by NMR spectroscopy, microanalysis and mass spectroscopy and was revealed to be in cone conformation. The application of Ni-NHC-calix[4]arene in Suzuki-Miyaura cross coupling showed moderate to good conversions. This is been depending on the length of the alkyl chain and the number of the catalytic centers grafted on the platform.Une série de calixarènes portant une unité imidazolium ou deux, en conformation cône ont été synthétisés et caractérisés par différentes méthodes. Ces sels chargés positivement...
