literature-known and novel S-containing pincer-type ligands for ruthenium-catalyzed homogeneous hydrogenation and dehydrogenation reactions was carried out. The scope and limitations of these catalysts were carefully investigated, and it was shown that simple bench-stable SNS–Ru complexes can be used to facilitate the hydrogenation of a variety of different substrates at a maximum H2 pressure of 20 bar under operationally

acid at either aryl or alkyl carbonatoms to afford, after reaction with lithium chloride in acetone, dimeric chloride bridged cyclopalladatedcomplexes in moderate (22%) to good (81%)yields. In these products each metal is part of a five-membered ring. The same reaction with 2-biphenyl methyl sulphide afforded a dimeric complex containing a six-membered cyclopalladated ring through palladation of the

Simple model systems based on the 2,11‐dithia[3,3]‐metaparacyclophane skeleton were synthesized to study the effects of substituents on the intramolecular aromatic–aromaticinteractions between benzene rings. X‐ray crystallography established that, in their more stable conformations, these metaparacyclophanes featured partially overlapping aromatic rings (interplanar distances of about 3.5 Å), with

methyl sulfide, benzyl phenyl sulfide and 1,3-bis(methylthiomethyl)benzene using Pd(OAc)2 can be accomplished using silica gel instead of a solvent. The yields of the corresponding cyclopalladated complexes in these green transformations are very similar to those obtained using conventional solvent conditions. The X-ray crystallographicdata for trans-Pd(HL)2Cl2 (HL = benzyl methyl sulfide) are reported

reaction of L with silver nitrate resulted in a 2-D coordination network 1, composed of metallomacrocycles bridged with NO3− ions. A 3-D framework 2 was observed when silver tetrafluoroborate was used. Although BF4− ions were not involved in coordinating with metal centers, the participation of water molecules led to a different metal–ligand binding mode and hence the formation of a network with higher dimension
