The dimethylamino functionality has significant importance in industrially relevant molecules and methodologies to install these efficiently are highly desirable. We report herein a highly efficient, room‐temperature dimethylamination of chloroheteroarenes performed via the in‐situ generation of dimethylamine using N,N‐dimethylformamide (DMF) as precursor wiith a large substrate scope that includes various heteroarenes, purines as well as commercially relevant drugs such as altretamine, ampyzine and puromycin precursor.

The present review devoted to the complete oxidation of CO using alkali-and alkaline-earth metal (AM/AEM)-modified ceria supported/mixed with noble metal and non-noble metal (NM). The AM/AEM-modified Ce supported/mixed with noble metal showed comparable CO oxidation with unmodified catalyst. However, AM/AEMmodified NM showed higher CO oxidation at lower temperature compared to the unmodified catalyst. The AM and AEM modifications were responsible for the formation of oxygen vacancies in Ce, which leads to the decrease in the CO and O 2 activation barrier. The dissociative oxygen adsorption on AM/AEM-modified Ce-supported/mixed with NM favours the CO oxidation at a lower temperature. However, AM/AEM-modified Ce-supported/mixed with noble metal showed CO adsorption with formation of superoxy and peroxy species, which leads to the comparable oxidation activity. The plausible mechanism for CO oxidation is explained in detail with correlation to the characterizations.
