“…Several other carbonyl compounds containing the GeFe 2 structural motif have been reported and characterized − as have complexes containing GeCo 2 triangles. − In addition, a number of higher nuclearity clusters containing μ 3 - 60-63 or μ 4 -germanium atoms, − ,− Ge 2 Fe 2 arrays, − or rings containing germanium, iron, and cobalt 62,72-75 are also known. The synthesis of these species typically involves using germanium(IV) precursors, while preparative routes involving the oxidation of germanium(II) precursors such as that employed for the synthesis of 7 are more uncommon.…”

The protonolysis reaction of the germanium(II) amide Ge[N(SiMe3)2]2 with calix[4]arene and calix[8]arene furnishes the two germanium(II) calixarene complexes {calix[4]}Ge2 and {calix[8]}Ge4, respectively, which have been crystallographically characterized. The calix[4]arene complex contains a Ge2O2 rhombus at the center of the molecule and is one of the only four germanium(II) calix[4]arenes that have been structurally characterized. The calix[8]arene species is the first reported germanium calix[8]arene complex, and it exhibits an overall bowl-shaped structure which contains two Ge2O2 fragments. The latter complex reacts with Fe2(CO)9 to yield an octairon compound, which has also been structurally characterized and contains four GeFe2 triangles arranged around the macrocyclic ring. The germanium(II) centers are oxidized to germanium(IV) in this process, with concomitant reduction of the neutral diiron species to Fe2(CO)(8)2- anions.

“…This bond-forming reaction could occur with the addition of a substrate molecule in whole or in part across the M−Ge moiety, with oxidation of the metal and/or oxidation of the germanium center, or with direct insertion into the M−Ge moiety with M−Ge bond cleavage. Numerous stable σ-bonded metal germylene complexes have been synthesized in the last few decades; − , however, comparatively fewer studies have emphasized the reactivity of the metal−germylene bond. ,,,,,− ,, …”

Sequential Insertion of Formaldehyde and Carbon Monoxide into a Sulfide-Bridged Pd−Ge Bond Followed by Reductive Elimination To Form a [1,3,2]Oxathiagermolan-4-one

The reaction of (2) with paraformaldehyde under photolytic conditions results in the insertion of formaldehyde into the Pd−Ge bond, with bond cleavage, to give (Et3P)2Pd(μ-S)(μCH2O)Ge[N(SiMe3)2]2 (3). Subsequent addition of CO to 3 results in migratory insertion into the Pd−C bond, followed by rapid reductive elimination to regenerate the Pd0 metal center and give a unique five-membered organic heterocycle, (6). The X-ray crystal structure of the dppe (dppe = bis(diphenylphosphino)ethane) derivative of 3, (dppe)Pd(μ-S)(μCH2O)Ge[N(SiMe3)2]2 (4), is reported.
