    Metal Carbonyls

    Numbers in square brackets refer to the List of Publications

    Our earlier activities in the chemistry of the Group 6 metal carbonyls were focussed at synthesis, spectroscopy, and the mechanism of substitution reactions. Lateron, special ligands such as sulfur dioxide [13, 18, 19, 22, 28, 30, 42, 50], carbon disulfide [15, 20, 27, 38, 39], thioesters [26, 33, 34], thioaldehydes [107, 110, 117], and sulfur-containing anions [124] were included with an emphasis on the reactions of coordinated ligands.

    Some anionic metal carbonyls (e.g. [W(CO)5(CN)]) are capable of migrating through the lipid bilayer membrane of living cells. With the goal of studying the associated physical phenomena we have now initiated a program to synthesize new anions of the type [W(CO)nX]. The group X is chosen as to provide the maximum lipophilicity (see Bioinorganic Chemistry).
