activation of secondaryamides in the presence of alkynes. An unusual mechanistic detour leading to pyridine derivatives as products is also presented and briefly discussed. In this article we describe the straightforward synthesis of polysubstituted pyrimidines by electrophilic activation of secondaryamides in the presence of alkynes. An unusual mechanistic detour leading to pyridine derivatives as products
Flow reactor approach for the facile and continuous synthesis of efficient Pd@Pt core-shell nanoparticles for acceptorless dehydrogenative synthesis of pyrimidines from alcohols and amidines
Carbonsupported Pd@Pt core-shellnanoparticles catalyst was prepared in a flow reactor toachieve enhanced catalyticactivities with low Pt loading for the acceptorless dehydrogenative synthesis of pyrimidines. Spectroscopic (XAS analysis) and microscopic (HAADF-STEM) techniques reveled that the core-shell structure was formed by the applied preparation method. The Pd@Pt/PVP (polyvinylpyrrolidone)/C
