The metal-free catalytic hydrogenolysis of silyl triflates and halides (I, Br) to hydrosilanes is unlocked by using arylborane Lewis acids as catalysts. In the presence of a nitrogen base, the catalyst acts as a Frustrated Lewis Pair (FLP) able to split H2 and generate a boron hydride intermediate capable of reducing (pseudo)halosilanes. This metal-free organocatalytic system is competitive with metal-based catalysts and enables the formation of a variety of hydrosilanes at room temperature in high yields (>85%) under a low pressure of H2 (鈮?0 bar). In the experiment, the researchers used many compounds, for example, 1,2,2,6,6-Pentamethylpiperidine (cas: 79-55-0Application of 79-55-0).
1,2,2,6,6-Pentamethylpiperidine (cas: 79-55-0) belongs to piperidine derivatives. The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper its spicy taste. Piperidine prefers a chair conformation, similar to cyclohexane. Unlike cyclohexane, piperidine has two distinguishable chair conformations: one with the N鈥揌 bond in an axial position, and the other in an equatorial position.Application of 79-55-0
