The metal-catalyzed addition of disilanes to unsaturated organic molecules—including alkenes, allenes, alkynes, carbonyls, and combinations of these groups—is reviewed, with emphasis given to synthetically useful transformations. Mechanistic details of the reaction are discussed. Examples of both intra- and intermolecular variants are given, with particular attention to reactions that proceed
