Suzuki triarylphosphine ligands

In continuation of the work on biphenyl tetraphosp tunes (see below), in 2014 Lv and Zhang and Zhang [61] reported the synthesis of biphenyl triarylphosphines (Scheme 2.22) for hydroformylation and studied the effect of external phosphines such as PPhg. The ligand backbone was constructed via Suzuki-Miyaura reaction, subsequent oxidation of the methyl groups, transformation ofthe formed carboxyl... 

Triarylphosphines with dendritically arranged tetraethyleneglycol moieties at the periphery were prepared according to Scheme 36 and were used as efficient ligands in the Pd-catalyzed Suzuki coupling. ...
