Aluminum(III) di- and monochlorides incorporating an N,N '-chelating iminophosphonamide ligand: synthesis and structures

摘要

Treatment of lithium iminophosphonamide with AlCl3 in Et2O led to the formation of an aluminum(III) dichloride complex as colorless crystals. The substitution reactions of aluminum(III) dichloride stabilized by an iminophosphonamide ligand with N- and Fe-nucleophiles gave the corresponding compounds of aluminum(III) monochloride. The reaction of the aluminum(HI) dichloride complex with CpNa proceeded slowly at room temperature to form an aluminum(III) monochloride complex bearing an eta(1)(sigma)-bonded cyclopentadienyl ring.
