这一观点讨论了烯烃、炔烃和其他不饱和C-C底物的催化加氢反应，其中催化剂的设计涉及到能够实现双功能H-2活化和输送的合作策略。这些方法补充了单一位置贵金属体系在均相催化中用于此类加氢反应的更传统的使用。这一观点中包括的战略是：(A)催化金属中心和碱性配体残基之间的合作，(B)催化金属中心和酸性配体残基之间的合作，(C)受挫的酸/碱对，以及(D)两个共催化金属中心之间的合作。强调了在催化转化中成功实施这些策略后出现的具有非贵重元素的独特的反应性和选择性模式。
This Perspective discusses catalytic hydrogenation reactions of alkenes, alkynes, and other unsaturated C-C substrates in which the catalyst design involves cooperative strategies that enable bifunctional H-2 activation and delivery. These approaches complement the more traditional use of single-site precious metal systems for such hydrogenation reactions in homogeneous catalysis. Strategies included in this Perspective are cooperation between (a) a catalytic metal site and a basic ligand residue, (b) a catalytic metal site and an acidic ligand residue, (c) frustrated acid/base pairs, and (d) two cocatalytic metal sites. Unique reactivity and selectivity patterns with nonprecious elements that have emerged from successful implementation of these strategies in catalytic transformations are emphasized.
