An efficient Ni-catalyzed hydrodifluoroalkylation of unactivated alkenes with bromodifluoroacetate by using PhSiH3 as hydride source was developed. The transformation affords aliphatic difluorides with anti-Markovnikov regioselectivity. A wide range of hi

A general catalytic base-controlled regiodivergent nucleophilic hydrofunctionalization of both terminal and internal β,γ-unsaturated amides has been reported. The atom-economical addition of various S/P-based nucleophiles was also exclusively chemoselective. More than 60 branched or linear hetero-substituted aliphatic amides were synthesized from common starting materials under transition-metal-free conditions. Preliminary mechanistic studies are consistent with our proposed divergent catalytic cycles.

Nickela-compounds with a five-membered ring, 4, are formed on Ni0 from CO2 and alkenes in the presence of the heterodifunctional ligand (cyclo-C6H11)2PCH2-CH2-2-pyridyl (2).A ring contraction occurs on addition of a promotor, such as BeCl2 or on heating.The greater reactivity of the nickela-complex with a four-membered ring, 6, can be used in the former reactions with CO2, CO or CH2=CH2.Such a sequence of reactions can be employed for the catalytic reaction of ethene with acrylic anilide on a (C6H11)3P/Ni0 system.
Nickel(0)-catalysed Synthesis of Unsaturated Carboxylic Acid Anilides from Ethene and Phenyl Isocyanate
Hoberg, Heinz,Hernandez, Elisa
, p. 544 - 545 (2007/10/02)
The first metal-catalysed synthesis of unsaturated carboxylic acid anilides from ethene and phenyl isocyanates is described; depending on the ligand, temperature, and pressure the anilides of acrylic and n-pentenoic acid can be formed selectively.

Cp2Tiη3-allyl and Cp2Tiη3-1-methylallyl react with carbon dioxide, phenylisocyanate, benzalaniline, acetone and acetonitrile to give insertion products which are formed via allyl migration.Normal insertion is observed with 2,6-xylylisocyanide.C
Titanium-promoted Allyl Transfer to Carbon Monoxide and Other Unsaturated Molecules
Klei, Bert,Teuben, Jan H.,Meijer, Henk J. de Liefde
, p. 342 - 344 (2007/10/02)
Carbonylation of Cp2Ti-(?-allyl) yields Cp2Ti(CO)2 and triallylmethanol; reactions of Cp2Ti-(?-allyl) and Cp2Ti-(?-1-methylallyl) with other ligands proceed via insertion or allyl-elimination pathways.
