A series of novel iridium(III) complexes containing 5-N-(aryl)-amino- or 5-cycloamino-3-(pyridine-2-yl)-1,2,4-triazine ligands was obtained. These exhibited red luminescence in solution as well the solid state. Based on DFT studies it suggested that N(2) atom 1,2,4-triazine core is preferable to N(4) one coordination site Ir(III).

In this work, we present a dedicated, high-throughput reaction optimization platform allowing for the rapid evaluation of regiodivergent C–H borylation protocols while minimizing amount starting material required. The workflow was applied to diverse set fragment-like compounds, pharmaceuticals, and agrochemicals, its practicality demonstrated by successfully isolating 36 derivatives bioactive compounds. Leveraging informer library approach, provide comprehensive, side-by-side comparison catalytic methods, revealing insights into strengths, limitations, versatility each protocol. Surprising reactivity patterns, effectiveness ligand-free borylation, utility previously reported directed catalysts outside their expected substrate scope have been noticed. This study highlights potential dedicated platforms expand practical late-stage functionalization pharmaceutical agrochemical research.

We have developed a BBr3-mediated, metal-free ortho C-H borylation of benzamides, enabling the synthesis wide range ortho-borylated benzamides in moderate to good yields. This transformation offers convenient strategy for accessing functionalized which are valuable intermediates pharmaceuticals, agrochemicals, and fine chemical synthesis.

Supramolecular catalysts based on a zinc-porphyrin molecular recognition site and catalytically active iridium enabled the selective ortho -C–H borylation of benzamides under regime in which C–H activation step is not rate-determining.

Direct borylation of C–H bonds is a privileged strategy to access versatile building blocks and valuable derivatives complex molecules (late-stage functionalization, metabolite synthesis). This perspective aims provide an overview classification the catalytic systems developed in this fast-growing area research. Unexpected selectivity differences between two established directed-borylation have been discovered using high-throughput experimentation highlighting importance classical control experiments catalysis
