The first total synthesis of the naturally occurring benzofurans, moracins O and P was achieved using a Sonogashira cross coupling reaction followed by in situ cyclization, and the absolute configuration of natural moracin O was established.

A straightforward, efficient, and reliable redox catalyst system for the Au(I)/Au(III)-catalyzed Sonogashira cross-coupling reaction of functionalized terminal alkynes with arylboronic acids under mild conditions has been developed.

A 2D porous carbon material with excellent electrochemical performance as an electrode in supercapacitors was synthesised using a Sonogashira–Hagihara cross-coupling/Bergman cyclization cascade reaction.

An efficient chemoselective process for the synthesis of 14- and 15-membered triazole-containing macrocycle compounds has been developed through the combination of two multicomponent reactions and an intramolecular Sonogashira cross-coupling reaction.

By a combination of kinetic and theoretical studies it is concluded that gold is intrinsically active to perform the Sonogashira coupling reaction between phenylacetylene and iodobenzene. The presence of Pd impurities is not mandatory for catalyst activity.

A microwave-assisted, one-pot, three-component coupling reaction for the synthesis of indoles has been developed. The reaction is carried out in two steps under standard Sonogashira coupling conditions from an N-substituted/N,N-disubstituted 2-iodoaniline and a terminal alkyne, followed by the addition of acetonitrile and an aryl iodide. A variety of polysubstituted indoles have been prepared i...

We have been interested in the development of polyalkynebased stars and dendrimers and their reactions with Co2(CO)8 to produce organometallic cluster-decorated architectures (Constable et al., 2006). We have used Sonogashira palladiumcatalysed cross-coupling reactions (Sonogashira et al., 1975; Sonogashira, 2002) for the divergent assembly of polyalkynes containing rigid frameworks with well-d...

The metastable tetragonal Cu2Se phase as nanoflakes has been synthesized for the first time by treating CuCl2 taken in a mixture (1:1) of 1-octadecene and oleylamine with H2N-(CH2)3-SePh dissolved in 1-octadecene. Powder X-ray diffraction (PXRD), HRTEM, SEM-EDX and XPS have been used to authenticate the nanoflakes. The XPS of Cu2Se nanoflakes indicates oxidation states of Cu and Se as +1 and -2...

This thesis focuses on the study of nickel boride as a catalyst in various coupling reactions. The nickel boride catalyst was investigated in three different coupling reactions, the experiments aimed at understanding the activity and catalytic properties of nickel boride. We successfully synthetized the nickel boride catalyst, alongside with the cobalt and iron boride. Different methods of prep...
