Chiral C 2 -symmetric bis(imidazoline) pincer ligands 2a–d have been synthesized for the first time. Direct cycloplatination of these ligands with K 2 PtCl 4 in dry acetic acid afforded the corresponding cycloplatinated pincer complexes 3a–d. The X-ray single-crystal structure of platinum complex 3d and the preliminary studies on the photoluminescent properties of 3 are reported.
[NiCl{C 6 H 3 -2,6-(OPPh 2 ) 2 }] efficiently catalyzes the thiolation of iodobenzene with a broad scope of disulfides in the presence of zinc, the coupled products are obtained in excellent and in many cases nearly quantitative yields.
