WebMar 20, 2008 · We describe the efficient preparation of Bippyphos, 1. The key precursor to Bippyphos, 5, was prepared via a one-pot bromination of diketone 2 followed by alkylation with pyrazole and condensation with phenylhydrazine. Lithiation of 5 and trapping with di- tert -butylchlorophosphine afforded Bippyphos, 1.

WebMar 18, 2024 · Among the ligands developed is BippyPhos. This ligand was originally designed to enable a coupling of primary amines with aryl halides. Further studies showed that the ligand has fairly broad utility for Pd-catalyzed C−N, C−O and C−C couplings. This review describes the various Pd-catalyzed applications involving BippyPhos as a … WebA search of the CAS compound database revealed a striking paucity of reported N,N-diaryl-sulfonamides: of the nearly one million reported tertiary ...
