Layered double hydroxides (LDHs) are recognized as two-dimensional (2D) clay materials, which comprise the interlayer anions and host layers with a positive charge (brucite-like M(OH)₆ octahedral). They have been used as effective and eco-friendly heterogeneous catalytic systems in cross-coupling reactions. In this review, we try to underscore the applications of (LDHs) as an efficient and green catalyst in some important name reactions, namely Suzuki, Heck, Sonogashira, and Ullmann cross-coupling reactions leading to carbon–carbon bond formations.

层状双氢氧化物作为交叉偶联反应中的非均相催化剂体系：概述

层状双氢氧化物 (LDH) 被认为是二维 (2D) 粘土材料，它包含层间阴离子和带正电荷的主体层（水镁石样 M(OH) ₆八面体）。它们已被用作交叉偶联反应中有效且环保的多相催化系统。在这篇综述中，我们试图强调（LDHs）作为一种高效和绿色催化剂在一些重要名称反应中的应用，即 Suzuki、Heck、Sonogashira 和 Ullmann 交叉偶联反应导致碳-碳键形成。
