Me6sn2 pd pph3 4
WebTreatment of Pd(acac)2 with PPh3 in alcohol or aldehydes at 70° is another method [36]. Heating Pd(N03)2 with PPh3 in a solution produces Pd(PPh3)4 [27]. Freshly precipitated palladium oxide reacts with PPh3 in ethanol to give Pd(PPh3)4 [27, 37]. Reaction of tris( dibenzylideneacetone )dipalladium with PPh3 in benzene or ether is an easy way ...
