A convenient and efficient method for the synthesis of α,β-alkynyl ketones from the three-component coupling of aryl iodides, terminal alkynes, and carbon monoxide (carbonylative Sonogashira coupling reaction) is successfully developed. The carbonylative Sonogashira coupling reaction proceeded smoothly under mild conditions in the presence of palladium nanoparticles to produce the corresponding α,β-alkynyl ketones in good to excellent yields.

An effective phosphine-catalyzed protocol has been established for the syntheses of 1,3-diketones and nitriles from alkynones with oximes as hydroxide surrogates. This method features the use of a phosphine catalyst, compatibility with various functional groups and ambient temperature, which makes this approach very practical. A plausible mechanism was proposed.

The development of new hydrogen-atom transfer (HAT) strategies within the framework of photoredox catalysis is highly appealing for its power to activate a desired C?H bond in the substrate leading to its selective functionalization. Reported here is the first photoredox-mediated hydrogen-atom transfer method for the efficient synthesis of ynones, ynamides, and ynoates with high regio- and chemoselectivity by direct functionalization of Csp2 (O)?H bonds. The broad synthetic application of this method has been demonstrated by the selective functionalization of C(O)?H bonds within complex molecular scaffolds.

Phosphorus- or sulfur-centered radicals generated from the reaction of manganese(III) acetate with dialkyl phosphonates or arylthiols undergo selective additions to conjugated alkynes followed by cyclization and rearomatization to afford 2-phosphonyl- or
Multi-Step synthesis by using modular flow reactors: The preparation of Yne-Ones and their use in heterocycle synthesis
Baxendale, Ian R.,Schou, Seren C.,Sedelmeier, Joerg,Ley, Steven V.
supporting information; experimental part, p. 89 - 94 (2010/03/03)
"Chemical Equation Presented" Multi-step in flow: The palladium-catalysed acylation of terminal alkynes for the synthesis of yne-ones as well as their further transformation to various heterocycles in a continuous-flow mode is presented. Furthermore, an extension of the simple flow configuration that allows for easy batch splitting and the generation of a heterocyclic library is described (see scheme).
