Sustainable technology for constructing Pd-catalyzed C–N bonds involving aliphatic amines is reported. A catalytic system that relies on low levels of recyclable precious metal, a known and commercially available ligand, and a recyclable aqueous mediumare combined, leading to a newly developed procedure. This new technology can be used in ocean water with equal effectiveness. Applications involving highly challenging reaction partners constituting late-stage functionalization are documented, as is a short but efficient synthesis of the drug naftopidil. Comparisons with existing aminations highlight the many advances being offered.

The article discusses the capability of wavelength stabilization technology for high-power laser diodes to bring an efficient spectral width that is locked over a wide temperature range. It notes that laser diodes are by a wide margin unsurpassed as efficient sources of radiation and have carved out dominant positions in many laser applications. The author points out that laser applications such as fiber-optic telecommunications and optical data storage would not exist at all without the diode.
