    • The structural data obtained for complex II revealed the presence of a bromide impurity, which was present in the original batch of 6 that produced the crystal (see Supporting Information). The data are satisfactorily modeled with the halide occupancy as 60% Br and 40% Cl.

    • The phenyl substituted ligands 1, 3, and 4 were much less effective in the Suzuki coupling or aryl chlorides. Ligand 6 showed comparable activity to 5 in several model studies. Also, a point of concern pertains to whether the tetraarylborate unit of ligand 5 is transferred during the cross-coupling reactions. While we cannot rule-out this possibility altogether, we note that tolylboronic acids were also screened briefly and found to give comparable yields.
