摘要

The betain like carbodiphosphorane CO2 adduct O2CC(PPh3)(2) (1a) can serve as a ligand versus hard Lewis acids from main group compounds. Thus, reaction of la with InCl3, InCl3 and SnCl2 in polar solvents leads to the addition compounds [Cl3In{O2CC(PPh3)(2)}] (2), [Cl2SnO2CC(PPh3)(2)}] (3) and the salt like compound [I3In{O2CC(PPh3)(2)}(2)]1 (4) in good yields. Whereas in the indium compounds la acts as a chelating ligand, in the tin compound the molecule coordinates with one oxygen atom only as a monodentate ligand. 4 has a pyramidal structure with a stereochemical active pair of electrons. All compounds could be characterized by X-ray analyses and the Usual spectroscopic methods.
