The two symmetry-independent molecules in the asymmetric unit of the title compound, C17H14N2S2, have similar geometry; the dihedral angles between the least-squares planes of the benzothiazole groups in the two molecules are 83.93 (3) and 81.26 (3)

Palladium(II)-catalyzed allylic acetoxylation has been the focus of extensive development and investigation. Methods that use molecular oxygen (O2) as the terminal oxidant typically benefit from the use of benzoquinone (BQ) and a transition-metal (TM

The design of a headspace pressure-monitoring reactor for measuring the uptake/evolution of gas in gas–liquid chemical transformations is described. The reactor features a parallel setup with ten-reactor cells, each featuring a low working volume o

The rational development of homogeneous catalytic systems for selective aerobic oxidations of organics has been hampered by the limited available knowledge of how oxygen reacts with important organometallic intermediates. Recently, several mechanisms

Allylic C–H acetoxylations are among the most widely studied palladium(II)-catalyzed C–H oxidation reactions. While the principal reaction steps are well established, key features of the catalytic mechanisms are poorly characterized, including th

Ruthenium complexes supported by two new CNN-pincer ligands were synthesized. Both were tested as catalysts for the hydrogenation of esters under mild conditions (105 °C, 6 bar H2). A striking dependence on ligand structure was observed, as a dimeth

Iridium complexes containing CCC-pincer m-phenylene-bridged N-heterocyclic carbene ligands were examined as catalysts for alkene isomerization. Complexes containing either mesityl or adamantyl side groups were found to catalyze the isomerization of a

The reaction of PEt2OH with K2PtCl4 yields [PtCl{(PEt2O)2H}]2 (2). The X-ray crystal structure of 2 shows that the two chloride ligands bridge the two Pt atoms. The structure is unusual in that the PtCl2Pt unit is bent, which is the first example of

The rates of nitrile hydration reactions were investigated using [Ru(η6-p-cymene)Cl2(PR2R′)] complexes as homogeneous catalysts, where PR2R′ = PMe2(CH2P(O)Me2), PMe2(CH2CH2P(O)Me2), PPh2(CH2P(O)Ph2), PPh2(CH2CH2P(O)Ph2), PMe2OH, P(OEt)2OH. These

The mechanism of the nitrile-to-amide hydration reaction using [Ru(η6-arene)Cl2(PR3)] complexes as catalysts was investigated (η6-arene = C6H6, p-cymene, C6Me6; R = NMe2, OMe, OEt, Et, iPr). Experiments showed that the mechanism involves the follow
