A series of seven novel N(Im)N(H)P-type pincer imidazolylphosphine ruthenium complexes has been synthesized and fully characterized. The use of hydrogenation of benzonitrile as a benchmark test identified [RuHCl(CO)(N(Im)N(H) P(tBu))] as the most active catalyst. With i...

Abstract A novel and convenient strategy toward caprolactam and butyrolactam derived phthalimide and amide scaffolds has been fulfilled through the palladium-catalyzed carbonylative coupling in a one-pot one step manner. The nucleophilicity of DBU and DBN was applied to...

Endohedral metallofullerenes (EMFs) are able to encapsulate up to four metal atoms. In EMFs, metal atoms are positively charged because of the electron transfer from the endohedral metal atoms to the carbon cage. It results in the strong Coulomb repulsion between the po...

The [2+2+2] cycloaddition reaction has become an invaluable tool for the synthetic chemistry in recent years, due to the increase of complexity of the accessed target molecules by this methodology. Over several decades, the members of group 9 of the periodic table have ...

At low catalyst loadings of Pd(OAc)2 (0.25-2.0 mol%) with PMI as ligand, aryl/heteroaryl chlorides or bromides are efficiently aminated by ammonia or primary and secondary amines.

Step in time: 2,5-Disubstituted furans can be prepared from terminal alkynes in one pot using two successive catalytic reactions (see scheme; p-TSA = para-toluenesulfonic acid). First, a 1,3-dienyl alkyl ether is produced by the dimerization of a terminal alkyne and add...

In the mid 1990s, we started a program on the development of more efficient palladium catalysts for the C–C and C–N coupling reactions of aryl halides, especially aryl chlorides. In this contribution, our investigations on new catalyst systems and their application in o...
