Tris(pentafluorophenyl)borane has been found to catalyze the two-fold C(sp3)?H silylation of various trialkylamine derivatives with dihydrosilanes, furnishing the corresponding 4-silapiperidines in decent yields. The multi-step reaction cascade involves amine-to-enamine dehydrogenation at two alkyl residues and two electrophilic silylation reactions of those enamines, one inter- and one intramolecular.

Paragraph 0107; 0108; 0109, (2017/09/01)
The embodiment of the invention discloses a fluorine-containing compound and a synthesis method thereof. The method comprises the steps of allowing a compound shown as formula (II) as shown in the specification and a compound shown as formula (III) as shown in the specification to react under the action of a fluorine reagent to generate: (1) the fluorine-containing compound shown as formula (I) as shown in the specification in the presence of water, and (2) the fluorine-containing compound shown as formula (IV) as shown in the specification in the absence of the water. The synthesis method of the fluorine-containing compound does not require a transition metal and is safer; the fluorine-containing compound is synthesized only by a one-step reaction; and the method is very simple and convenient.

Dialkylformamides are excellent N-sources in the amination of benzyl chlorides when catalysed by a NHC-Pd(II)-Im complex. In the presence of NaOH and the catalyst, variously substituted benzyl chlorides and five different dialkylformamides reacted smoothly to afford the corresponding N,N-dialkyl-benzylamines in good to almost quantitative yields in eco-friendly solvent water at 50 °C within 3 h.
