A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 250285-32-6, Name is 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride, molecular formula is C27H37ClN2.

The paper describes three methods for the preparation of methoxysiloxide complexes, a rare class of complexes of relevance to room temperature vulcanization (RTV) of polysiloxanes. The salt metathesis reaction involves the use of the recently described reagent NaOSi(OMe)2Me with various metal chlorides to give Cp?2Ti[OSi(OMe)2Me](OMe), (Me,MeN2N)NiOSi(OMe)2Me, (IPr)CuOSi(OMe)2Me, and (triphos)CoOSi(OMe)2Me (Cp? = C5Me5, triphos = Me(CH2PPh2)3). Several attempted reactions gave methoxide complexes instead, a pathway that is attributed to the intermediacy of kappa2-OSi(OMe)2Me species. The diol Cp?2Zr(OH)2 reacts with excess (MeO)3SiMe to give Cp?2Zr[OSi(OMe)2Me]2. In contrast the less nucleophilic Cp?2Ti(OH)2 was unreactive. The third route to methoxysiloxide complexes involves the reaction of Cp?2M(O)(py) with (MeO)3SiMe to give Cp?2M[OSi(OMe)2Me](OMe) in nearly quantitative yield (M = Ti, Zr). The structures of Cp?2Ti[OSi(OMe)2Me](OMe), Cp?2Zr[OSi(OMe)2Me](OMe), (IPr)CuOSi(OMe)2Me, and (triphos)CoOSi(OMe)2Me were confirmed by single crystal X-ray diffraction.
