The copper-catalysed cycloaddition of alkynes and azides to form 1,2,3-triazoles has emerged as a powerful tool in ligand design and the synthesis of novel transition metal complexes. In this review we focus on the photophysical properties of metal complexes bearing 1,2,3-triazole-based ligands with a particular emphasis on those of d 6 metals including rhenium(I), iron(II), ruthenium(II), osmium(II) and iridium(III). We also highlight key examples of triazole complexes of platinum(II) and palladium(II) as well as the lanthanides and coinage metals. 1. Introduction 2.

“…Standard Suzuki protocol, treatment with one equivalent of arylboronic acids or dioxaborolanyle 116 in the presence of tetrakis(triphenylphosphine)palladium(0) [Pd(PPh 3 ) 4 ] and alkali carbonates, gives moderate yields of monoaryl benzothiadiazoles 117 only (Scheme 55). 19,114 The yields can be improved up to 85%, if non-symmetrical NCP-pincer palladacycle (115) in the presence of cesium fluoride is used. The standard Suzuki conditions, reaction with boronic acids, tetrakis (triphenylphosphine)palladium(0) [Pd(PPh 3 ) 4 ] and alkali carbonates, were used to prepare benzothiadiazoles containing one bromine (Figure 4).…”
