%X We report a re-examination of Trofimenko&#x2019;s original protocol for the preparation of the acid form of his hydrotris(pyrazolyl)borates, H(TpR,R&#x2032;), by the treatment of M(TpR,R&#x2032;)with glacial acetic acid. It is concluded that the protocol is effective as long as the 3-substituent of the pyrazolyl moiety is sufficiently bulky to provide steric protection to the acidic N&#x2013;H proton. The solid-state structure of H(TptBu,Me), the acid form of the popular TptBu,Me ligand is also presented.
