Abstract:
The ligand (i-Pr)2PCH2(oxazoline) (1a), of the P,N-donor type, was reacted with PdMeCl(COD)] to yield the square planar methylpalladium(II) complex PdClMe(P,N)] (P,N = 1a) (2a), from which the complex PdMe(P,N)OTf] (OTf = OSO2CF3) (3a) was obtained by AgOTf-promoted chloride abstraction. The alkyl complexes
