Procedure for the synthesis of Palladium(0) Complex
The title compound was synthesized according to the new procedure presented below.
Bis(tris(o-tolyl)phosphine)(dibenzylideneacetone)palladium(0) – [Pd(2-dba)(P(o-tolyl)3)2]32 (3):
Pd(dba)2 (0.3 g, 5.22 x 10-4 mol), tris(o-tolyl)phosphine (0.321 g, 1.054 x 10-3 mol) were placed in a
Schlenk flask (25 mL) and degassed for one minute. Afterwards, 4 mL toluene (0.125M) was
introduced into vigorously stirred solids of substrates and the final mixture was left for 8h at room
temperature to give a yellow-orange solution. The excess of the solvent was evaporated under
reduced pressure. The procedure was followed by the addition of hexane. As a result a yellow-orange
precipitate was observed. Next, the precipitate was filtered (‘canula’ system), washed with cold
hexane (4 x 10 mL) and dried in vacuum for 2h. The crude product was obtained with 93% (460 mg,
yellow-orange solid) yield. Elemental analyses calcd. for C60H58OP2Pd: C 74.80, H 6.07; found C 74.78,
H 6.06.

X-Ray structure determination
Excalibur four-circle diffractometer with Eos CCD-detector, using MoKα radiation source (λ = 0.7107
Å). The data was corrected for Lorentz-polarization as well as for absorption effects.38 Accurate unit-
cell parameters were determined by a least-squares fit of 1984 reflections of highest intensity,
chosen from the whole experiment. The structures were solved with SIR9239 and refined with the
full-matrix least-squares procedure on F2 by SHELXL97.40 All non-hydrogen atoms were refined
anisotropically. The hydrogen atoms were placed geometrically, in idealized positions, and refined as
rigid groups with their Uiso’s as 1.2 times Ueq of the appropriate carrier atom. Crystallographic data
(excluding structure factors) for the structural analysis has been deposited with the Cambridge
Crystallographic Data Centre, No. CCDC 974168. Copies of this information may be obtained free of
