“…[27b] These ligands have been synthesized using a modular one-pot synthesis (Scheme 1, see ligands 1 and 2 in Figure 12). [33] The positively charged [Cu 3 I 2 (N-P) 3 ] + ion forms a trigonal bipyramidal array, with three Cu I ions and two iodides forming a trigonal bipyramid, in which the three Cu I ions occupy the equatorial and the two iodide ions the axial positions (Scheme 1, right side). Each Cu I ion is coordinated by one P and one N donor of the auxiliary bridging NHetPHOS ligands.…”

Easy come, easy go: the great structural diversity of Cu(I) complexes is an ambivalent trait. Apart from the well-known catalytic properties of Cu(I), a great number of potent luminescent complexes have been found in the last ten years featuring a plethora of structural motifs. The downside of this variety is the undesired formation of other species upon processing. In here, strategies to avoid this behavior are presented: Only one favorable structural unit often exists for multinuclear Cu(I) complexes with bridging ligands. In addition, these complexes exhibit favorable photophysical properties due to cooperative effects of the metal halide core. Furthermore, we demonstrate the broad range of applications of emitting Cu(I) compounds.

Triazole‐based phosphanes have recently been shown to be interesting ligands in organometallic catalysis. The synthesis of novel [2.2]paracyclophane‐substituted triazole‐based phosphane ligands was achieved. The possibility to synthesize these molecules in a highly enantioenriched form is also reported. Moreover, the ability of the novel ligands to coordinate with metal centers was explored. Besides a dinuclear copper complex, a PdII complex could also be isolated, the structure of which was characterized by X‐ray analysis. PdII complexes derived from these ligands provide highly active catalysts for the Suzuki–Miyaura coupling of aryl chlorides.

Heterocyclic phosphines have long been used as unique and efficient ligands for palladium-catalyzed cross-coupling reactions. The simplest ligand, trifurylphosphine, has become one of the most classical heterocyclic phosphines for coupling reactions since its first application in the Stille coupling reaction in 1988. In recent decades, palladium catalyst systems derived from highly diverse and innovative heterocyclic phosphines have shown excellent catalytic activities in cross-coupling reactions. In this account, we discuss the recent development and applications of heterocyclic phosphine ligands, highlighting the synthetic pathways used to prepare the ligands. The sections are categorized by the different palladium-catalyzed cross-coupling methodologies.
