is dependent on the number of HBC substituents. The crystalline structures of five complexes all show intramolecular π-stacking between HBC-phosphines to form a supramolecular bidentate-like ligand that distorts the metal coordinationgeometry. When n = 2 or 3, the additional HBC substituents engage in intermolecular π-stacking to assemble the complexes into continuous ribbons or sheets. The phosphines

Efficient, phosphine‐directed ortho C−H borylation of arylphosphine derivatives was achieved using Ru catalysts for the first time. The reaction is applicable to various tertiary arylphosphine and arylphosphinite derivatives to give (o‐borylaryl)phosphorus compounds in high yields. This reaction enables easy access to a variety of functionalizedphosphine ligands and ambiphilic phosphine boronate compounds
The versatile preparation of new anionic water-soluble ligands derived from triphenylphosphane is described based on halogen-lithium exchange followed by CO2 quenching. Efficient inter- and intramolecular Heck reactions have been disclosed. Comparison with other anionic and cationic ligands showed that meta substitution on the aromatic ring enhanced the reactivity.
