“…Another documented solution to the problem is stepwise transition-metal-catalyzed hydrosilylation of unsaturated hydrocarbons with dichlorosilane, obtainable in bulk quantities. [2][3][4][5] The accumulation of salt waste is another penalty often encountered when converting the aforementioned silanes into the corresponding hydrosilanes by hydride reduction, typically with LiAlH 4 ( Figure 1A). What is missing is the custom synthesis of hydrosilanes R 4-n SiH n , where n = 3, 2, and 1, based on the simplest silicon molecule, i.e., monosilane, as a platform.…”
