Cross-coupling Reactions of Monosubstituted Tetrazines [PDF]

open access: yesOrganic Letters, 2021
A Ag-mediated Pd-catalyzed cross-coupling method for 3-bromo-1,2,4,5-tetrazine with boronic acids is presented. Electronic modification of the 1,1′-bis(diphenylphosphine)ferrocene (dppf) ligand was found to be crucial for good turnover. Using this fast method, a variety of alkyl-, heteroatom-, and halide-substituted aryl- and heteroaryl-tetrazines were

Cross-Coupling of Heteroatomic Electrophiles [PDF]

open access: yesChemical Reviews, 2019
At the advent of cross-coupling chemistry, carbon electrophiles based on halides or pseudohalides were the only suitable electrophilic coupling partners. Almost two decades passed before the first cross-coupling reaction of heteroatom-based electrophiles was reported.

Stereoretentive radical cross-coupling. [PDF]

open access: yesNature
Free radicals were first discovered more than 120 years ago by Gomberg1 and the first radical cross-couplings demonstrated by Kochi in the 1970s (ref. 2). In contrast to widely used polar cross-coupling chemistry to forge C(sp2)-C(sp2) bonds (such as Suzuki, Negishi and Kumada), radical cross-coupling is advantageous when applied to the coupling of ...

Pd-Catalyzed Cross-Coupling of Alkylbisboronic Esters. [PDF]

open access: yesChemistryOpen
A Pd‐catalyzed cross‐coupling between alkylbisboronic esters and aryl bromides is described. A variety of aryl bromides are found to be competent substrates in the reaction.

Stabilized Arylzinc Iodides in Negishi Acylative Cross-Coupling: A Modular Synthesis of Chalcones

open access: yesOrganics, 2022
Stabilized arylzinc iodides, synthesized by direct insertion of zinc into the corresponding halides, were used as nucleophiles into an acylative Negishi coupling reaction to synthesize chalcones.

Cross-coupled DOA trackers [PDF]

open access: yesIEEE Transactions on Signal Processing, 1997
A new robust, low complexity algorithm for multiuser tracking is proposed, modifying the two-stage parallel architecture of the estimate-maximize (EM) algorithm. The algorithm copes with spatially colored noise, large differences in source powers, multipath, and crossing trajectories.

Denitrative Cross-Couplings of Nitrostyrenes [PDF]

open access: yesMolecules, 2020
Interestingly, β-nitrostyrenes, typically bench stable compounds, are highly promising cross-coupling partners, due to their excellent availability and well understood reactivity. In this review, we report on the discovery and advancements, in the field of stereoselective, denitrative cross-couplings of β-nitrostyrenes with miscellaneous organic ...

Convergent cross sorting for estimating dynamic coupling

open access: yesScientific Reports, 2021
Natural systems exhibit diverse behavior generated by complex interactions between their constituent parts. To characterize these interactions, we introduce Convergent Cross Sorting (CCS), a novel algorithm based on convergent cross mapping (CCM) for ...

New insight in Hiyama cross-coupling reactions: Decarboxylative, denitrogenative and desulfidative couplings [PDF]

open access: yesChemical Review and Letters, 2018
In this mini-review, recent advances and developments in the decarboxylative, denitrogenative, and desulfidative Hiyama-type cross-coupling reaction from 2011 up present are studied.
