Pd[P(tBu)3]2 reacts photochemically with an excess of phenol in n-hexane to give the dinuclear complex [{P(tBu)2H}2Pd2{μ-P(tBu)2}(μ-η2:η2-C6H5O)] [BOND] 3 C6H5OH (1); X-ray crystallography shows a linear chain of three phenol molecules hydrogenbonded to the phenoxide ligand which is η4-coordinated to the Pd2 framework. The π coordination of the phenoxide ring is retained in solution, as evidenced by 1H-NMR spectroscopy.

Abstract
Pd[P(tBu)3]2 reacts photochemically with an excess of phenol in n-hexane to give the dinuclear complex [{P(tBu)2H}2Pd2{μ-P(tBu)2}(μ-η2:η2-C6H5O)] [BOND] 3 C6H5OH (1); X-ray crystallography shows a linear chain of three phenol molecules hydrogenbonded to the phenoxide ligand which is η4-coordinated to the Pd2 framework. The π coordination of the phenoxide ring is retained in solution, as evidenced by 1H-NMR spectroscopy.File in questo prodotto:
