Reaction of the ortho-metalated arylhydrazido complex BF4 with hydrogen chloride occurs without rupture of the Ir-ortho-carbon bond.The products are dependent on the experimental conditions.In organic solvents a 1/1 HCl adduct is produced, in which addition of HCl across the Ir-N multiple bond has occurred to give the ortho-metalated arylhydrazine complex BF4.In liquid hydrogen chloride reaction also occurs at the metalated aromatic ring, involving chloride substitution at the 3-position and conversion of the 2-nitro group to 2-nitroso.The structure of this complex has been determined by X-ray crystallography.
