WebJul 31, 2015 · The metal-free activation of hydrogen reported in 2006 using the concept of FLPs (20, 21) led to an important breakthrough in the metal-free hydrogenation reaction . In FLP processes, cleavage of H 2 occurs via the cooperation of a Lewis acid and a Lewis base that are prevented from forming a Lewis adduct by steric or geometrical constraints. WebNov 23, 2024 · Abstract. This chapter provides a brief overview of the evolution of FLP catalysis. We begin with a description of the initial finding of reversible hydrogen activation and the development of FLP-mediated catalytic hydrogenations. Subsequently, the applications of FLPs in other catalytic processes involving other small molecules are …
In terms of mechanism, the alkyne material is first hydroborated and then the resulting vinylborane-based FLP can then activate dihydrogen. A protodeborylation step releases the cis -alkene product, which is obtained due to the syn -hydroborylation process, and regenerating the catalyst. See more A frustrated Lewis pair (FLP) is a compound or mixture containing a Lewis acid and a Lewis base that, because of steric hindrance, cannot combine to form a classical adduct. Many kinds of FLPs have been devised, and … See more Imine, nitrile and aziridine hydrogenation Reduction of imines, nitriles, and aziridines to primary and secondary amines traditionally is effected by metal hydride reagents, e.g. lithium aluminium hydride and sodium cyanoborohydride.
