cross-coupling
[/krɔːs ˈkʌplɪŋ/]
nounpl: cross-couplings
acoplamento cruzado
1. A chemical reaction in which two carbon-containing organic compounds are joined together using a metal catalyst, typically palladium
The cross-coupling reaction between the aryl halide and organoboron compound produced the desired biaryl product.
A reação de acoplamento cruzado entre o haleto arílico e o composto organoboro produziu o produto biaril desejado.
2. In physics and engineering, the phenomenon where vibrations or oscillations in one system are transferred to another coupled system
The cross-coupling between the two mechanical oscillators caused unexpected resonance patterns.
O acoplamento cruzado entre os dois osciladores mecânicos causou padrões de ressonância inesperados.
3. In control systems, the unwanted interaction between different control loops or system variables
The engineers had to compensate for cross-coupling effects in the multi-axis motion control system.
Os engenheiros tiveram que compensar os efeitos de acoplamento cruzado no sistema de controle de movimento multi-eixo.
Cross-coupling reactions are a cornerstone of modern organic synthesis and pharmaceutical development. The term gained prominence following the 2010 Nobel Prize in Chemistry awarded to Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki for palladium-catalyzed cross couplings in organic synthesis. In Brazil and Portugal, this technique is extensively studied in chemistry departments and is fundamental to drug discovery and materials science research.
