Abstract:
Activation of the C-X (X = I, Br, Cl) bond in four N-aryl benzaldimine ligands (L1-L4), bearing halogen atoms at both the ortho-positions of the phenyl ring in the benzaldimine fragment, was successfully brought about via interaction of these ligands with the electron-rich Ru(0) center in [Ru(CO)3(PPh3)2], leading to the formation of four cyclometalated complexes of ruthenium(II) (C1-C4). Crystal structures of all of the complexes were determined. The demonstrated ability of the Ru(0) center in [Ru(CO)3(PPh3)2] to activate the C-halogen bond was also exploited in catalytic Suzuki-type C-C cross-coupling reactions between aryl halides and aryl boronic acids.

Radical Substitution: Hydrogenolysis of Alkyl Halides with Tributyltin Hydride
The bonds formed in this reaction are stronger than the bonds broken, making it energetically favorable. The reaction follows a radical chain mechanism similar to radical halogenation...
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.

The mechanism starts with chain initiation, which involves two steps. In the first chain initiation step, a weak peroxide bond is homolytically cleaved upon mild heating to form two alkoxy radicals. In the second initiation step, a hydrogen atom is abstracted by the alkoxy...
