Palladium-catalysed synthesis of triaryl(heteroaryl)methanes
Tetraarylmethane derivatives are desirable for a variety of applications, but difficult to access with modern C-C bond-forming reactions. Here we report a straightforward method for palladium-catalysed arylation of aryl(heteroaryl)methanes and diaryl(heteroaryl)methanes with aryl chlorides. This reaction enables introduction of various aryl groups to construct triaryl(heteroaryl)methanes via a ...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولPalladium-catalysed direct synthesis of benzo[b]thiophenes from thioenols.
The one-pot conversion of thioenols into benzo[b]thiophenes was achieved by using a simple palladium catalyst such as PdCl(2) or PdCl(2)(cod).
متن کاملSynthesis of fused tetracyclic spiroindoles via palladium-catalysed cascade cyclisation.
Efficient palladium-catalysed cascade cyclisation to form spiroindoles is developed. Treatment of indoles bearing a propargyl chloride side chain at the 3-position with various external nucleophiles in the presence of a catalytic amount of Pd2(dba)3·CHCl3/dppb and Cs2CO3 in THF gives fused tetracyclic spiroindoles in moderate to good yields.
متن کاملPalladium catalysed aryl enol ether synthesis from vinyl triflates.
Vinyl triflates can be efficiently converted into the corresponding aryl enol ethers by treatment with a phenol, NaO(t)Bu and a catalyst generated from Pd2dba3 and 2-(di-(t)Bu-phosphino)biphenyl.
