X-ray analysis of diisopropylammonium tert-butylmethylphosphinite borane 4 revealed the existence of a cyclic hydrogen-bond network in the solid state which accounts for the increased melting point and stability. Dialkylammonium phosphinite boranes are convenient precursors of the chiral tert-butylmethylphosphine fragment. Compound 4 can be directly employed in SN2@P reactions with different nucleophiles to yield valuable P-stereogenic intermediates and ligands.5 p.application/pdfeng(c) American Chemical Society, 2017Lligands (Bioquímica)Compostos fosforososCatàlisi asimètricaLigands (Biochemistry)Phosphorus compoundsEnantioselective catalysisinfo:eu-repo/semantics/article2017-07-25info:eu-repo/semantics/openAccess28640640
