The full scope and limitations of solution and solid phase one-pot three component Nacyliminium ion reactions are detailed. After studying the scope in solution with respect to the carbamate, nucleophile and aldehyde component, a ‘translation’ was made to the solid phase. The solid phase reactions were eventually carried out using the so-called SEC linker system, which was previously developed ...

Platinum extraction from different secondary sources has been experimentally tested by many researchers. In this article, dissolution of platinum in aqua-regia solution from two types of spent catalysts (reforming and nitric acid production) was kinetically studied. A variety of kinetic models for heterogeneous solid-liquid reactions, including homogeneous diffusion model, shrinking core model,...
