Copper catalyzed cross-coupling reactions of carboxylic acids: an expedient route to amides, 5-substituted γ-lactams and α-acyloxy esters
TL;DR: In this article, a convenient and recyclable catalytic protocol for the synthesis of N,N-dimethyl substituted amides, 5-substituted γ-lactams and α-acyloxy ethers from carboxylic acids using CuO nanoparticles and TBHP is described.
Journal ArticleDOI
Investigation of the scope and mechanism of copper catalyzed regioselective methylthiolation of aryl halides
TL;DR: In this paper, aryl halides were methylated under fluoride free conditions using catalytic amounts of CuI, and DMSO as the methylthiolation source.
Journal ArticleDOI

S. Priyadarshini,P. J. Amal Joseph,P. Srinivas,H. Maheswaran,M. Lakshmi Kantam,Suresh K. Bhargava +5 more
TL;DR: An efficient and inexpensive protocol for the Sonogashira-type cross coupling reactions of phenylacetylenes with a variety of haloarenes including activated aryl chlorides employing the structurally well-characterized bis(μ-iodo)bis((−)-sparteine)dicopper(I) catalyst is described in this article.
Journal ArticleDOI
Copper catalyzed ipso-nitration of iodoarenes, bromoarenes and heterocyclic haloarenes under ligand-free conditions
TL;DR: A catalytic protocol for the conversion of haloarenes into the corresponding nitroarenes is presented using copper salts under ligand-free conditions and was effectively utilized for the ipso-nitration of a broad variety of h Haloarenes that includes iodoarene, bromoarenes, and heterocyclic haloarernes.
Journal ArticleDOI
Catalytic guanylation of aliphatic, aromatic, heterocyclic primary and secondary amines using nanocrystalline zinc(II) oxide
M. Lakshmi Kantam,S. Priyadarshini,P. J. Amal Joseph,P. Srinivas,Ajayan Vinu,Kenneth J. Klabunde,Yuta Nishina +6 more
TL;DR: Nanocrystalline ZnO was found to be a highly efficient heterogeneous catalyst for the guanylation of amines with various carbodiimides to afford N,N′,N″-trisubstituted guanidines in excellent yields as discussed by the authors.
