Alkynylation of graphene via the Sonogashira C-C cross-coupling reaction on fluorographene
We report successful grafting of alkynyl groups onto graphene via the Sonogashira reaction between fluorographene and terminal alkynes. Theoretical calculations revealed that fluorographene can efficiently bind and oxidize the palladium cata...

[2+2+2]-Cocyclotrimerization of 6-Alkynyl-7-benzylpurines with alpha,omega-Diynes
6-Alkynyl-7-benzylpurines were prepared by the Sonogashira reaction from 6-chloro-7-benzylpurines and terminal alkynes. The prepared alkynylpurines were cyclotrimerized with various 1,6-diynes in the presence of Ni(cod)2/2PPh3 catalytic syst...

Imidazole-Fused Enediynes by Selective C5-C4 Alkynylations of 4,5-Dibromoimidazoles
An efficient synthesis of symmetrical 1,2-disubstituted 4,5-dialkynylimidazoles by Sonogashira alkynylation of the corresponding 4,5-dibromo derivatives was developed. Moreover, through a careful tuning of the palladium ligand, unsymmetrical...
