Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. SDS of cas: 32005-36-0. Introducing a new discovery about 32005-36-0, Name is Bis(dibenzylideneacetone)palladium

Several new neutral and cationic organopalladium complexes containing a P-N chelating ligand, 2-(diisopropylphosphinomethyl)-1-methylimidazole, have been synthesized and characterized. The neutral complexes [PdPh(I)(P-N)] 1 and [PdMe(I)(P-N)] 2 have been synthesized by oxidative addition of PhI and MeI, respectively to Pd(dba)2 (dba = dibenzylideneacetone) in the presence of the P-N ligand. The cationic complexes [PdPh(PPh3)(P-N)]BF4 3 and [PdMe(PPh3)(P-N)]BF4 4 were obtained by adding an acetone solution of AgBF4/PPh3 to the corresponding neutral precursors 1 and 2, respectively. A cationic allyl complex, [Pd(eta3-C3H5)(P-N)]Br 5, has also been prepared by oxidative addition of 3-bromopropene to Pd(dba)2 in presence of the P-N ligand. Single crystal structure determinations have been carried out for 1, 4 and 5. Carbonylation of the metal-carbon bond in these new complexes was also studied. The neutral complexes 1 and 2 react smoothly with CO to give carbonylated products [Pd(C(O)Ph)I(P-N)] 6 and [Pd(C(O)Me)I(P-N)] 7, respectively. The methyl complex 2 reacted much faster than the phenyl complex 1. The cationic complexes 3 and 4 are inert and do not give any carbonylated product. However, in the case of the reaction of 3, evidence has been obtained for the formation of a CO-coordinated complex [PdPh(PPh3)(CO)(P-N)]BF4 8 in which the P-N ligand temporarily acts as a monodentate phosphorus-bonded ligand. On the other hand, a cationic complex containing a weakly coordinating acetone molecule, [PdMe{(CD3)2CO}(P-N)]BF4 9, showed an enhanced reactivity toward CO and gave [Pd{MeC(O)}(CO)(P-N)]BF4 10.
