Abstract

Molecules of the general formula [R2MFe(CO)4]2, M = Ge, Sn, or Pb, readily and reversibly undergo homolytic cleavage by relatively weak Lewis bases to produce tetracarbonyliron complexes of the general formula base · R2M→Fe(CO)4. The relative cleavage propensity for metals is Ge > Sn ≥ Pb and for bases is pyridine > acetone > tetrahydrofuran > diethyl ether. It is seen that diaryl- and dialkylgermylenes, -stannylenes, and -plumbylenes, when coordinated to a transition metal, can still function as strong Lewis acids.
