The moles of each reagent are changed in each flask in order to demonstrate the limiting reagent concept. In flasks 1 and 2, a small amount of Mg is used and therefore the metal is the limiting ...

The direct transfer of primary amino and hydroxyl groups to arylmetals in a scalable and environmentally friendly fashion remains a formidable synthetic challenge. Here, it is demonstrated that ...

"Acetalization, a well-known reversible reaction between carbonyl compounds and alcohols, usually need excess of one of the reactant to compel reversible acetalization completion," Li said, ...

Excess reagents can be easily removed, and purification achieved, by washing. Solid-phase methods are widely used for the synthesis of biological molecules such as peptides, ...

Bio-catalysis offers a renewable, energy efficient, low waste, and affordable strategy for the synthesis of fine chemicals and commodities. The synthesis of many chemicals requires high temperatures, ...

Excess reagents as well as coupling and cleavage related by-products are solely removed by aqueous extractions. Therefore, intermediate isolation of the tag-bound peptide and excessive washing steps ...
