13-trien-18-oate does not. Carbonylation of the cyclopalladated 1-tetralone oxime complexes in methanol gives the corresponding 8-methoxycarbonyl-1-tetralone oximes. Hydrogen-1 n.m.r. analysis of 1-tetralone oxime and Li2[PdCl4] solutions show [PdCl2(oxime)2] is not a reaction intermediate. At –76 °C co-ordinated oxime exhibits a downfield shift for H8, characteristic of above-plane geometry of the ligand
