Metal Reactivity on Oxo Surfaces Modeled by Calix [4]arenes:Metal-Driven Reactions in an Oxo-Quasiplanar Environment

摘要

A quite recent molecular approach to metaloxo surfaces uses as a model the preorgainsed O_4 set of donor atoms derived from the calix [4] arene tetraanion and its alkylated forms. Metals bonded to such an environment assist:1)the formation of C-C and C=C bonds by multiple migratory insertion reactions;2) olefin rearrangement to M-C,M=C,M ident to C occurring under very mild conditions;3) the activation and reduction of dinitrogen with a complete N ident to N triple bond cleavage.
