Cleavage of H-C(sp2) and C(sp2)-X Bonds (X = Alkyl, Aryl, OR, NR2): Facile decarbonylation, isonitrile abstraction, or dehydrogenation of aldehydes, esters, amides, amines, and imines by [RuHCl(PiPr3)2]2

The RuHClL2 fragment (L = PiTr3) reacts at 25 °C with a dozen different G=CHE compounds (G = O, E = R, OR, NR2; G = NR, E = R) to give π-acid abstraction products, RuHCl(CG)L2, and E-H. For E-H = C2H5OH, alcohol is decarbonylated in a second step to give an additional CO ligand and CH4. For E-H = HNR(CR′2H), amine can be dehydrogenated by RuHClL2 to give RuH(H2)ClL2 and CR′2=NR. X-ray crystallographic studies are presented for the DMF decarbonylation intermediate Ru(H)2Cl(η2-C(O)NMe2)L2, where the strong reducing potential of RuHClL2 is manifested in the formally Ru(IV) species obtained from oxidative addition of H-C(O)NMe2. The structure of Ru(H2)Cl(η2-C6H4CH=NMe)L 2, the product from aryl C-H activation of benzylidenemethylamine, PhHC=NMe, is also presented. This ability to abstract CO, isonitrile, or H2 is traced to the considerable π-basicity of RuHCl(PiPr3)2.
