Abstract:

Aryl benzoates are compounds of high importance in organic synthesis. Herein, we report the iron-catalyzed C(sp2)–C(sp3) Kumada cross-coupling of aryl chlorobenzoates with alkyl Grignard reagents. The method is characterized by the use of environmentally benign and sustainable iron salts for cross-coupling in the catalytic system, employing benign urea ligands in the place of reprotoxic NMP (NMP = N-methyl-2-pyrrolidone). It is notable that high selectivity for the cross-coupling is achieved in the presence of hydrolytically-labile and prone to nucleophilic addition phenolic ester C(acyl)–O bo

We report the synthesis and characterization of meso-anthracenylporphyrins with zinc and nickel metal centers. A variety of novel aryl and alkyl meso-substituted anthracenylporphyrins were synthesized via step-wise Suzuki cross-coupling reactions using anthracenyl boronates. This method was compared to standard syntheses based on condensation reactions to yield anthracenylporphyrins of the A2B2- and A3B-type. The work was complemented by the synthesis of a number of the functionalized anthracene derivatives via Suzuki couplings. Selected systems were subjected to single-crystal X-ray analysis

Abstract:

While the advent of transition-metal catalysis has undoubtedly transformed synthetic chemistry, problems persist with the introduction of secondary and tertiary alkyl nucleophiles into C(sp2) aryl electrophiles. Complications arise from the delicate organometallic intermediates typically invoked by such processes, from which competition between the desired reductive elimination event and the deleterious β-H elimination pathways can lead to undesired isomerization of the incoming nucleophile. Several methods have integrated distinct combinations of metal, ligand, nucleophile, and electrophile t

Iron links a trio Iron holds particular appeal as a catalytic metal—it is safe and abundant, as well as a mainstay of enzymatic reactivity. Nonetheless, in synthetic construction of carbon-carbon bonds, modern chemists have largely had to rely on rarer metals such as palladium. Liu et al . now report that coordination of iron by a bulky chelating phosphine ligand enables efficient mutual coupling of three different reactants—an alkyl halide, an aryl Grignard, and an olefin—to form two carbon-carbon bonds (see the Perspective by Lefèvre).

A practical procedure for the cleavage of alkyl aryl ethers containing labile functional groups has been developed using aluminum triiodide as the ether cleaving reagent.

The method is applicable to variant alkyl aryl ethers such as eugenol, vanillin, ortho-vanillin and methyl eugenol. Suitable substrates are not limited to alkyl o-hydroxyphenyl ethers.

Abstract:

A nickel-catalyzed cross-electrophile coupling of aryl triflates and nonaflates with alkyl iodides using manganese(0) as a reductant is described. The method is applicable to the reductive alkylation of various aryl sulfonates, including o-borylaryl triflate, which enabled efficient construction of diverse alkylated arenes under mild conditions.

Abstract:

A straightforward synthesis of alkyl-sulfonylpyridines and aryl-sulfonylpyridines is developed by coupling of sulfonylpyridines with the Grignard reagents. The protocol proceeds through a catalyst- and oxidant-free coupling of sulfonylpyridines as substrates via a Chichibabin-type reaction mechanism.
