Proton-induced reactivities of ruthenium azido complexes: the first example of boron-carbon bond formation by methylene insertion into a B-H bond

Whereas the reaction of Tp(PhCN)(PPh(3))Ru-N(3) {Tp = HB(pz)(3), pz = pyrazolyl} with CH(3)I in CH(2)Cl(2) led to the cationic ruthenium methyleneimine complex [Tp(PPh(3))(PhCN)Ru(NH=CH(2))]I, the analogous reaction with HCl gave rise to the ruthenium chloride complex containing a methyl tris(pyrazo...

Summary:Whereas the reaction of Tp(PhCN)(PPh(3))Ru-N(3) {Tp = HB(pz)(3), pz = pyrazolyl} with CH(3)I in CH(2)Cl(2) led to the cationic ruthenium methyleneimine complex [Tp(PPh(3))(PhCN)Ru(NH=CH(2))]I, the analogous reaction with HCl gave rise to the ruthenium chloride complex containing a methyl tris(pyrazolyl)borate ligand (Me)Tp(PPh(3))(PhCN)RuCl, as a result of the highly unusual methylene insertion into a B-H bond of the Tp ligand.
