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. 1118-61-2, Name is 3-Aminocrotononitrile, molecular formula is C4H6N2.

Bifunctional Rhodium Complex Featuring a Silyl-1,8-naphthyridine Si,N-Chelate Ligand: Cooperation of Metal and Pendant Base for Capture and Bond-weakening of BH3
A dirhodium complex bearing a newly-designed silyl-1,8-naphthyridine ligand (napySi), [Rh(kappa Si-2,N-napySi)(H)(mu-Cl)](2) (1), was synthesized. Reaction of complex 1 with excess BH3 center dot SMe2 afforded a mononuclear borane adduct Rh[kappa Si-4,N,H,H-napySi(BH3)](H)Cl (2), revealing that rhodium and the uncoordinated naphthyridine nitrogen cooperatively captured BH3 and weakened its two B-H bonds. Complex 2 contains a Rh(mu-H)(2)B core composed of two Rh-H-B-3-center 2-electron (3c-2e) bonds where one Rh-H interaction is considerably weakened by strong trans-influence of the silyl ligand moiety.
