A review. Numerous ligands have been designed for the Buchwald-Hartwig Amination (BHA). 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 supporting ligand. While BippyPhos may not often be the most optimal ligand for various Pd-catalyzed couplings, it typically will provide adequate results as a starting point prior to screening for optimization.

We describe the efficient preparation of Bippyphos I [R = P(t-Bu)2] (II). The key precursor to Bippyphos, I (R = H) (III), was prepared via a one-pot bromination of diketone PhCOCH2COPh followed by alkylation with pyrazole and condensation with phenylhydrazine. Lithiation of III and trapping with di-tert-butylchlorophosphine afforded Bippyphos II. Using this approach we have prepared several derivatives of Bippyphos to probe the structure and activity relationships of this family of phosphine ligands. We also demonstrate the utility of these ligands in Pd-catalyzed amination reactions and other cross-coupling reactions.

Minimal buried volume of the phosphine ligands was correlated with the stoichiometry of nickel and palladium complexes and catalytic activity in Suzuki, Heck and Buchwald amination reactions. Chemists often use statistical anal. of reaction data with mol. descriptors to identify structure-reactivity relationships, which can enable prediction and mechanistic understanding. In this study, we developed a broadly applicable and quant. classification workflow that identifies reactivity cliffs in 11 Ni- and Pd-catalyzed cross-coupling datasets using monodentate phosphine ligands. A distinctive ligand steric descriptor, min. percent buried volume [%Vbur (min)], is found to divide these datasets into active and inactive regions at a similar threshold value. Organometallic studies demonstrate that this threshold corresponds to the binary outcome of bisligated vs. monoligated metal and that %Vbur (min) is a phys. meaningful and predictive representation of ligand structure in catalysis.

Hydration of C≃C bond is a very efficient synthetic step. Currently, there exist ruthenium catalytic complexes, preferably with phosphine or bipyridine ligands, able to hydrate with “”anti-Markovnikov”” selectivity, producing aldehydes. Although development of novel hydration catalysts was fruitful in recent years, only very few mechanistic studies of mol. structural influences are described. On the model hydration or 1-heptyne, we tested a series of various organophosphine ligands with various nitrogen functionalities having different acid-base properties. This screening showed that ligands with methylene-substituted nitrogen in five-membered ring are very promising to synthesize a catalyst for anti-Markovnikov hydration of alkynes.
