Transition-Metal-Free Cross-Coupling of Aryl and Heteroaryl Thiols with Arylzinc Reagents
Yang, Bo,Wang, Zhong-Xia
, p. 6220 - 6223 (2017/11/24)
Cross-coupling of (hetero)arylthiols with arylzinc reagents via C-S cleavage was performed under transition-metal-free conditions. The reaction displays a wide scope of substrates and high functional-group tolerance. Electron-rich and -deficient (hetero)arylthiols and arylzinc reagents can be employed in this transformation. Mg2+ and Li+ ions were demonstrated to facilitate the reaction.

experimental part, p. 632 - 643 (2012/03/27)
Four new grid forming hydrazone ligands substituted with methoxy and dimethylamino groups were synthesised. Combination of these ligands with zinc triflate in acetonitrile resulted in self-assembly to form grids as indicated by 1H NMR and ES-MS

An improved and convenient methodology for the synthesis of asymmetrically substituted pyrazines starting from 3,5-dichloropyrazin-2(1H)-ones has been elaborated. Several nucleoside analogues have been synthesized containing the pyrazine core as the organic base coupled with the sugar via a triazole linkage. The beneficial effect of microwave irradiation throughout the sequence has been demonstrated.
A convenient method for the preparation of highly substituted 1101 pyrimidines: Synthesis of tri- and tetra-subsituted pyrimidines from 1,3-dicarbonyl compounds and N,N,N′-tris-(trimethylsilyl)amidines
Ghosh, Usha,Katzenellenbogen, John A.
, p. 1101 - 1104 (2007/10/03)
A modification of the Pinner pyrimidine synthesis has been developed that utilizes trimethylsilyl amidines and results in greatly improved yield of highly substituted pyrimidines.
SYNTHESIS OF PYRIMIDINYL TRIFLATES AND PALLADIUM-CATALYZED COUPLING WITH ORGANOTIN AND ORGANOZINC REAGENTS
Sandosham, Jessie,Undheim, Kjell
, p. 501 - 514 (2007/10/02)
Pyrimidinyl triflates have been synthesized from pyrimidinones using triflic anhydride in the presence of triethylamine.The triflates, in the pyrimidine electrophilic positions, are versatile intermediates for substitution reactions.Carbon substituents ar
