obtained as the single E isomer in 80% yield by treating the enantiopure ketone with N,N-dimethylhydrazine in the presence of an equimolar amount of p-toluenesulfonic acid in ethanol. Direct cyclopalladation of hydrazone 1 was accomplished at the C(3)H2 group using [Pd(MeCN)2Cl2] and NaOAc in MeCN at the reflux temperature. The product of the reaction, dinuclear cyclopalladated complex 2, was isolated
