Conditions are reported for the facile, high-yielding coupling of acyl chlorides with terminal alkynes in a reaction involving palladium and copper iodide; the reaction is tolerant of a wide variety of acyl chlorides and terminal alkynes and provides a convenient one-pot route to acetylenic ketones.

In continuation of previous work sensitization experiments have been made with various substances such as urushiol, benzyl chlorides, and acyl chlorides. In the case of a series of substituted benzenes (Cl, NO(2)) a connection between sensitizing capacity and lability of the Cl or NO(2) groups has been shown, indicating the formation of conjugated antigens in the animal. This led to the study o...

A simple and reliable method, based on that described by W. Seubert (1960, Biochem Prep. 7, 80-83), has been developed for the chemical synthesis of radioactive acyl coenzyme A’s. I-14C-labeled fatty acids (palmitic, oleic, and linoleic) are converted to their acyl chlorides with oxalyl chloride. The [l-14C]acyl chlorides are then condensed with a twoto three-fold molar excess of coenzyme A in ...

We describe here an atom efficient procedure to prepare selenol esters in good to excellent yields by reacting [(PhSe)₂Zn] or [(PhSe)₂Zn]TMEDA with acyl chlorides under "on water" conditions. The method is applicable to a series of aromatic and aliphatic acyl chlorides and tolerates the presence of other functionalities in the starting material.

Visible light photoredox/nickel dual catalysis has been employed in the cross-coupling of acyl chlorides with potassium alkyltrifluoroborates. This protocol, based on single-electron-mediated alkyl transfer, circumvents the restriction of using reactive alkylmetallic nucleophiles in transition-metal-catalyzed acylation and achieves a mild and efficient method for the synthesis of unsymmetrical ...

α-Isocyanoacetamides, acyl chlorides and dialkylacetylenedicarboxylates undergo a smooth multicomponent reaction to produce dialkyl 2-acyl-5-aminofuran-3,4-dicarboxylates in good yield. The scope and mechanism of this new multicomponent transformation are discussed.

Palladium-catalyzed cross-coupling of acyl chlorides with potassium perfluorobenzoates to synthesize perfluorinated biaryls has been reported, which realized the first example involving simultaneous decarbonylation and decarboxylation under redox-neutral conditions.

The grafting of drugs to the single-walled carbon nanotube (SWCNT) was attained by the initial conversion of carboxylic groups in SWCNT to corresponding acyl chlorides. The active acyl chlorides in SWCNT were subsequently mixed with chemotherapeutic agents having NH, NH2, and OH functional groups to afford the formation of relevant amide and ester, respectively. The covalently grafted drugs to ...

The addition of ynamides to acyl chlorides and N-heterocycles activated in situ with ethyl chloroformate has been accomplished at room temperature using copper iodide as catalyst. This economical and practical carbon-carbon bond formation provides convenient access to a variety of 3-aminoynones from aliphatic and aromatic acyl chlorides in up to 99% yield. The addition to pyridines and quinolin...

Synthesis of 3,1,5-benzoxadiazepines from the condensation of o-phenylenediamine (o-PDA) and acyl chlorides in the presence of a catalytic amount of various heteropolyacids (HPAs) is reported.
