Thiophene-based donor–acceptor co-oligomers by copper-catalyzed 1,3-dipolar cycloaddition
Beilstein J. Org. Chem. 2012, 8, 683–692, doi:10.3762/bjoc.8.76
- –donor type, in which thiophene moieties work as donor and 1,2,3-triazoles as acceptor units. In this respect, terminally ethynylated (oligo)thiophenes were coupled to halogenated (oligo)thiophenes in the presence of sodium azide and a copper catalyst. Optoelectronic properties of various thiophene-1,2,3
Nano copper oxide catalyzed synthesis of symmetrical diaryl sulfides under ligand free conditions
Beilstein J. Org. Chem. 2011, 7, 886–891, doi:10.3762/bjoc.7.101
- -smelling thiols as the main drawback, which leads to environmental and safety problems. To overcome these problems, Zhou [43] and coworkers recently reported an efficient C–S bond formation by the reaction of potassium thiocyanate and aryl halides in the presence of a copper catalyst and a ligand in
Gold-catalyzed naphthalene functionalization
Beilstein J. Org. Chem. 2011, 7, 653–657, doi:10.3762/bjoc.7.77
- % with respect to the diazo compound). Similarly to the previous results, the fused norcaradiene 3a (Scheme 5) was exclusively and quantitatively formed using the copper catalyst 1a, whilst the use of 1b afforded a mixture of three products in a 60:20:20 ratio. The major product was identified as the 3a
Efficient 1,4-addition of α-substituted fluoro(phenylsulfonyl)methane derivatives to α,β-unsaturated compounds
Beilstein J. Org. Chem. 2008, 4, No. 17, doi:10.3762/bjoc.4.17
- enones can be used to introduce difluoromethylene moiety while Kumadaki and coworkers [21][22] have used bromodifluoroacetate with a copper catalyst to introduce the CF2 functionality. There also exist few reports on the 1,4-addition of monofluoromethylene moieties to α,β-unsaturated compounds [23][24
