Bis(dimethylgermyl)alkane-iron tetracarbonyls: Synthesis, photolysis, and reactivity

This work concerns the synthesis, spectroscopic analysis, and reactivity of tetracarbonyliron bis(dimethylgermyl)alkanes Me2Ge(CH2)nGe(Me2)Fe(CO)4 (n = 1, 2). These heterocycles are obtained by cyclization of bis(dimethylgermyl)alkanes Me2HGe(CH2)nGeHMe2 (n = 1, 2) with Fe(CO)5 under UV irradiation. They are stable at room temperature, but the heterocycle with n = 1 decomposes under prolonged UV irradiation with formation of the heterocycle with n = 2, perhydrotetragermin, and (CO)3Fe(μ-GeMe2)3Fe(CO)3. Various CO substitution reactions with phosphines and cleavage reactions with organic and organometallic halides are described; they provide a convenient procedure for the generation of germanium or tin-carbonyl iron clusters. Reactions of tetracarbonyliron bis(dimethylgermyl)methane with sulfur and with oxygen presumably lead first to the dithia- (or dioxa-) digermolane Me2GeCH2Ge(Me2)Y-Y (Y = S or O) and after, by sulfur (or oxygen) loss, to thia- (or oxa-) digermetane Me2GeCH2GeMe2Y (Y = S or O), which are unstable, giving products suggestive of Me2GeY (Y = O or S) and Me2Ge=CH2 intermediates.
