The coupling of aryl or vinyl halides with terminal acetylenes catalysed by palladium and
other transition metals, commonly termed as Sonogashira cross-coupling reaction, is one of …

Covering: January 1995 up to the end of 2008 Natural stilbenes have been a hot research
topic due to their intricate structures and diverse biological activities. Although their …

Research on natural products containing benzofuran has remarkably increased during the
past few decades. Newly isolated natural products with complex structures are being …

Benzofuran derivatives are ubiquitous in natural products,[1] agrochemicals,[2]
pharmaceuticals,[3, 4] and organic materials.[5] Particularly, 2-arylbenzofurans are widely …

Symmetrical diarylalkynes were obtained from propiolic acid (or 2-butynedioic acid) and aryl
halides in good yields. The optimized reaction conditions were 2.0 equiv of aryl halide, 1.0 …

Conclusions In this review, we have presented numerous very useful processes for the
synthesis of heterocycles, which involve palladium-catalyzed coupling followed by …

2-Octynoic acid and phenylpropiolic acid were employed for the palladium-catalyzed
decarboxylative coupling reaction and with a variety of aryl halides. The former needed 1, 4 …

An impregnated copper on magnetite catalyst is a versatile system for different domino
Sonogashira-cyclization processes between 2-iodophenol and different alkynes to give the …

A new and convenient metal-free cyclization of ortho-hydroxystilbenes into 2-
arylbenzofurans and 2-arylnaphthofurans mediated by hypervalent iodine reagents is …

Diarylalkynones were synthesized from one-pot Pd-catalyzed carbonylative and
noncarbonylative coupling reactions of propiolic acid with aryl iodides under a carbon …
