Iron(II) Clathrochelate with Terminal Triple C-C Bond and Its Carboranoclathrochelate Derivative with a Flexible Linker between the Polyhedral Cages: Synthesis and X-Ray Structure

摘要

Monopropargylamine iron(II) tris-dioximate was easily prepared in a high yield using nucleophilic substitution of its monochlor- oclathrochelate precursor with propargylamine as a primary aliphatic amine N-nucleophile in acetonitrile as a solvent. This complex with terminal C?C group underwent a 1,3-dipolar cycloaddition “click”-reaction with ortho-carborane-1-meth- ylazide, thus giving a hybrid iron(II) carboranoclathrochelate with ortho-carborane-(12)-[1,2,3]-triazolmethylamine fragment in its ribbed substituent, the molecule of which contains two (i. e. clathrochelate and carborane) terminal cages.
