Carbon-silicon and carbon-carbon bond formation by elimination reactions at metal N-heterocyclic carbene complexes.
Two functional groups can be delivered at once to organo-rare earth complexes, (L)MR(2) and (L)(2)MR (M = Sc, Y; L = ({1-C(NDippCH(2)CH(2)N)}CH(2)CMe(2)O), Dipp = 2,6-(i)Pr(2)-C(6)H(3); R = CH(2)SiMe(3), CH(2)CMe(3)), via the addition of E-X across the metal-carbene bond to form a zwitterionic imidazolinium-metal complex, (L(E))MR(2)X, where L(E) = {1-EC(NDippCH(2)CH(2)N)}CH(2)CMe(2)O, E is a p...
متن کاملSynthesis and carbon-carbon bond-forming reactions of tungsten, molybdenum, and rhenium enolates
Alkylation of sodium cyclopentadienyl(tricarbonyl)metal— lates of tungsten and molybdenum with o—chloro ketones and c—chloro esters gives stable tungsten and molybdenum enolates (23a—23d). Similar alkylation of sodium pentacarbonylrhenate provides rhenium enolates 24. Compounds 23 lOse carbon monoxide and rearrange to 3—oxaallyl complexes 25 upon irradia— tiøn. Compounds 25 react with benzaldeh...
متن کاملCarbon-carbon bond forming reactions with substrates absorbed non-covalently on a cellulose chromatography paper support.
Reactions and purifications, including carbon-carbon bond forming reactions, can be carried out on a cellulose support on which the substrates are non-covalently absorbed.
متن کاملNickel-catalyzed carbon-carbon bond-forming reactions of unactivated tertiary alkyl halides: Suzuki arylations.
The first Suzuki cross-couplings of unactivated tertiary alkyl electrophiles are described. The method employs a readily accessible catalyst (NiBr(2)·diglyme/4,4'-di-tert-butyl-2,2'-bipyridine, both commercially available) and represents the initial example of the use of a group 10 catalyst to cross-couple unactivated tertiary electrophiles to form C-C bonds. This approach to the synthesis of a...
متن کاملPhosphinocyclodextrins as confining units for catalytic metal centres. Applications to carbon–carbon bond forming reactions
The capacity of two cavity-shaped ligands, HUGPHOS-1 and HUGPHOS-2, to generate exclusively singly phosphorus-ligated complexes, in which the cyclodextrin cavity tightly wraps around the metal centre, was explored with a number of late transition metal cations. Both cyclodextrin-derived ligands were assessed in palladium-catalysed Mizoroki-Heck coupling reactions between aryl bromides and styre...
