with (MeCN)4Pd(BF4)2 in the presence of triphenylphosphine to give stable 1/1 complexes in good yields. 1,1′-Bis(alkylseleno)ferrocenes and 1,1′-bis(phenylthio and phenylseleno)ferrocenes to give similar 1/1 complexes. Some platinum analogs were prepared from the reaction of the corresponding dichloro-complexes with AgBF4 in the presence of triphenylphosphine. The spectral data indicate that there is
