Efficient and chemoselective imine synthesis catalyzed by a well-defined PN-manganese(II) pincer system.

The highly efficient reductive amination of aldehydes with ammonia (NH) and hydrogen (H) to form secondary imines is described, as well as the dehydrogenative homocoupling of benzyl amines. Using an air-stable, well-defined PN-manganese(II) pincer complex as a catalyst precursor, various aldehydes are easily converted directly into secondary imines using NH as a nitrogen source under H in a one-pot reaction. Importantly, the same catalyst facilitates the dehydrogenative homocoupling of various benzylamines, exclusively forming imine products.

Efficient and chemoselective hydrogenation of aldehydes catalyzed by well-defined PN-pincer manganese(II) catalyst precursors: an application in furfural conversion.

Well-defined and air-stable PN-pincer manganese(II) complexes were synthesized and used for the hydrogenation of aldehydes into alcohols under mild conditions using MeOH as a solvent. This protocol is applicable for a wide range of aldehydes containing various functional groups. Importantly, α,β-unsaturated aldehydes, including ynals, are hydrogenated with the CC double bond/CC triple bond intact.

Technical and economic potentials of the unconventional extruded dried Arabic bread wastes in broilers diets.

Food waste is one of the major global challenges that have adverse socioeconomic and environmental impacts. Therefore, studying food waste utilization potentials and minimizing its negative consequences becomes imperative. This study aims to assess the technical and economic potentials of substituting corn with unconventional extruded dried Arabic Bread waste (EDABW) in broilers' diets, in terms of broilers' performance, carcass characteristic, economic net returns, and income over feed cost (IOFC).

Cobalt-Catalyzed Selective Hydrogenation of Nitriles to Secondary Imines.

The first example of cobalt-catalyzed selective hydrogenation of nitriles to secondary imines is reported. The results demonstrate the significantly different selectivity compared with the previously reported cobalt catalytic system during the nitrile hydrogenation. A variety of aromatic and aliphatic nitriles are hydrogenated to the corresponding secondary imines.

Optimizing coffee cultivation and its impact on economic growth and export earnings of the producing countries: The case of Saudi Arabia.

Coffee is one of the historical socioeconomic crops. It has received an increasing attention at the global level, due to its positive interlinkage with the economic growth and on the gross domestic product for most of the producing countries, particularly, developing and least developed countries. Saudi Arabia is one of the coffee producing countries that has a relative comparative advantage of coffee cultivation.
