The addition of a Y–H (Y = B, Si, Sn, N, P, and O) bond and H₂ to unsaturated bonds is a powerful and atom-economic method for the synthesis of fine chemicals. In the recent years, magnesium-based organometallic complexes have appeared as an alternative to transition metal catalysts for the hydrofunctionalization and hydrogenation of unsaturated systems. This review focuses on the progress of magnesium catalysis for the hydrofunctionalization and hydrogenation of unsaturated bonds, provides a critical assessment of the state-of-the-art research, highlights the major developments achieved in the past three years, and provides an overview of the challenges and opportunities.

将 Y–H（Y = B、Si、Sn、N、P 和 O）键和 H _{2 添加}到不饱和键是合成精细化学品的一种强大且原子经济的方法。近年来，镁基有机金属配合物已成为过渡金属催化剂的替代品，用于不饱和体系的加氢官能​​化和加氢。本综述重点关注镁催化在不饱和键的加氢官能​​化和加氢方面的进展，对最新研究进行了批判性评估，重点介绍了过去三年取得的重大进展，并概述了挑战和机遇。
