Conspectus Low molecular weight gases (eg, carbon monoxide, hydrogen, and ethylene)
represent vital building blocks for the construction of a wide array of organic molecules …

This review article will consider the preparation and application of ynones in synthetic
organic chemistry. Concerning the preparation of these bifunctional compounds, several …

Oxidative carbonylation using carbon monoxide has evolved as an attractive tool to valuable
carbonyl-containing compounds, while mixing CO with a stoichiometric amount of a …

Transition metal catalyzed carbonylation reactions using carbon monoxide as the C-1
source have occupied an all important position in catalysis which is subsequently related to …

Herein, we report a ligand-controlled palladium-catalyzed method that enables the synthesis
of ynones and γ-butenolides with excellent regioselectivity from the same set of readily …

This Review examines parts per million (ppm) palladium concentrations in catalytic cross-
coupling reactions and their relationship with mole percentage (mol%). Most studies in …

The direct acyl Sonogashira cross-coupling of carboxylic acids with terminal alkynes has
been achieved through Pd/Cu cooperative catalysis. In this reaction, the readily available …

A palladium-catalyzed CO gas-free carbonylative Sonogashira/cyclization sequence for the
preparation of functionalized 4-quinolones from 2-iodoanilines and alkynes via two different …

The first palladium-catalyzed Sonogashira coupling of amides has been developed, which
proceeds via a selective cleavage of the N-acylsaccharin C–N bond. Notably, the new …

A practical palladium‐catalyzed carbonylative Suzuki coupling of aryl halides under carbon
monoxide gas‐free conditions has been developed. Here, formic acid was utilized as the …
