Are there alternatives to Rhenium(III) iodide (CAS: 15622-42-1) in synthesis?

Rhenium(III) iodide (CAS: 15622-42-1) is a potent reagent for organometallic reactions. While it is highly effective, alternatives such as rhenium trichloride and rhenium pentachloride can be considered in certain synthesis scenarios. Other metal iodides and complexing agents may also serve as substitutes depending on the specific reaction conditions and desired outcomes.
