Unprecedented double migratory insertion of phenyl isocyanide into cyclopentadienyl C-H bonds.
The reaction of [(eta(5)-C(5)H(5))Cu(CNPh)] with phenyl-isocyanide results in an unprecedented double migratory insertion into two sp(2) C-H bonds of a eta(5)-coordinated cyclopentadienyl group, and formation of the 6-aminofulvene-2-aldimine complexes [(CNPh)Cu{kappa(2)-N,N-C(5)H(3)-1,2-(CHNPh)(2)}] and [(CNPh)(2)Cu{kappa(2)-N,N-C(5)H(3)-1,2-(CHNPh)(2)}], respectively, both of which have been s...
متن کاملCatalytic carbon insertion into the β-vinyl C-H bond of cyclic enones with alkyl diazoacetates.
The first example of the boron Lewis acid catalyzed C(sp2)-H functionalization of cyclic enones was achieved using diazoacetates. The insertion of the carbon atom of diazoacetates utilizes BF3•Et2O or a newly designed oxazaborolidinium ion as a catalyst to afford β-functionalized cyclic enones from simple cyclic enones in a single step and high yields. The reaction mechanism was investigated wi...
متن کاملCatalytic enantioselective carbon insertion into the β-vinyl C-H bond of cyclic enones.
Chiral oxazaborolidinium ion-catalyzed Csp(2)-H functionalization of enones using diazoacetate has been developed. Various β-substituted cyclic enones were synthesized in high yield (up to 99%) with high to excellent enantioselectivity (up to 99% ee). The synthetic utility of this reaction was demonstrated by the formal synthesis of (+)-epijuvabione.
متن کاملAn insertion scheme for C n crystals
We dene bumping and sliding algorithms for the C n tableaux of Kashiwara and Nakashima. Together, they are used to dene an insertion scheme for such tableaux which turns out to be a crystal isomorphism.
متن کاملStille coupling via C–N bond cleavage
Cross-coupling is a fundamental reaction in the synthesis of functional molecules, and has been widely applied, for example, to phenols, anilines, alcohols, amines and their derivatives. Here we report the Ni-catalysed Stille cross-coupling reaction of quaternary ammonium salts via C-N bond cleavage. Aryl/alkyl-trimethylammonium salts [Ar/R-NMe3]+ react smoothly with arylstannanes in 1:1 molar ...
