metal−carbonylate salts [(η5-C5H5)M(CO)n]−Na+ (M = Fe (n = 2), Mo, W (n = 3)) and ClCH2GeR2Cl result in the high-yield formation of (η5-C5H5)M(CO)nGeR2CH2Cl (M = Fe, R = Me (1), n-Bu (2); M = Mo, R = Me (3), R = n-Bu (4); M = W, R = Me (5), R = n-Bu (6)). Complexes 1, 2, 5, and 6 are transformed into the isomers (η5-C5H5)M(CO)nCH2GeR2Cl (1a, 2a, 5a, and 6a) thermally and/or photochemically. Treatment of either type
