ACS Appl Mater Interfaces

January 2025

CSIR-National Physical Laboratory, Dr. K.S. Krishnan Marg, New Delhi 110012, India.

In the past decade, significant efforts have been made to develop efficient half-Heusler (HH) based thermoelectric (TE) materials. However, their practical applications remain limited due to various challenges occurring during the fabrication of TE devices, particularly the development of stable contacts with low interfacial resistance. In this study, we have made an effort to explore a stable contact material with low interfacial resistance for an n-type TiCoSb-based TE material, specifically TiNbCoSbBi as a proof of concept, using a straightforward facile synthesis route of spark plasma sintering.

Org Biomol Chem

January 2025

Henan Provincial Engineering and Technology Research Center for Precise Synthesis of Fluorine-Containing Drugs. College of Chemistry and Chemical Engineering, Anyang Normal University, Anyang, 455000, P. R. China.

A TEMPO-mediated β-ketoalkylation of enaminoesters with cyclopropanols under metal-free conditions is herein described. This reaction provides a straightforward and highly efficient route to β-keto alkyl substituted enaminoesters for the first time, which could be rapidly and efficiently converted into synthetically useful 2-alkoxycarbonyl functionalized 1,5-diketones. Moreover, the practicability of this protocol is successfully demonstrated by scale-up experiments and the late-stage functionalization of natural products and pharmaceutically relevant molecules.
