Capturing a ghost. synthesis and structural characterization of Pd(dba)[P(o -Tol)3]2
In an effort to improve upon a literature synthesis of bis[tris(o-tolyl) phosphine]palladium(0) (1) from tris(o-tolyl)phosphine and Pd 2(dba)3, we instead isolated a new compound which proved to have the composition Pd(dba)[P(o-Tol)3]2 (2), upon analysis by X-ray crystallography. While this is not the first known palladium compound containing both dba and phosphine ligands, it is, to our knowledge, the first containing dba and tris(o-tolyl)phosphine. This is significant, because mixtures of Pd2(dba)3 and tris(o-tolyl)phosphine are routinely used in cross-coupling protocols, and palladium complexes containing dba and tris(o-tolyl)phosphine have been cited as intermediates in organometallic and polymerization reactions. The most interesting crystallographic parameter for 2 is an abnormally long Pd-P bond length of 2.388(1) A, which we believe is the cause of this complex’s metastability. We also present an alternative synthesis of 1 that does not require a large excess of phosphine.
