At low temperatures C₅Hr₅Rh(CO)L, 1 (L = P(CH₃)₂C₆H₅), reacts with Cl₂, Br₂, CH₃COBr, and CF₃COCl forming isolable [C₅H₅Rh(CO)LX] ⁺X^- or [C₅H₅Rh(CO)L(COR)] ⁺X^- which were converted to their more stable tetraphenylboron salts. At room temperature the ionic dihalides lose CO forming neutral C₅H₅RhLX₂. Alkyl halides (CH₃Cl, CH₃Br, CH₃I, C₃H₅Cl) react with 1 forming acyl derivatives C₅H₅RhL(COR)X in a reaction thought to proceed via ionic [C₅H₅Rh(CO)LR] ⁺X^-.
