Formation of thermally unstable complexes [Mn(CO)2CpMe(R2PO-TEMP)] (Cp = cyclopentadienyl; Me = methyl; TEMP = 2,2,6,6-tetramethyl-piperidin-1-oxyl) is presented in this experimental and theoreticalstudy; in case of R = Cy 31P NMR spectroscopic evidence is provided. Mechanistic details of the product formation and decomposition, due to a homolytic O–N bond cleavage, are revealed by high-level density

and NMR spectroscopy. The μ-phosphido complex [FeMn(μ-CO)(μ-PPh2)(CO)2(Cp)(C5H4Me)] has been prepared analogously from [Fe(CO)2(PPh2)(Cp)] and [Mn(CO)2(thf)(C5H4Me)]. Variable temperature NMR spectra of the latter heterodinuclear complex, in CDCl3, show the presence of an equilibrium mixture of the two interconverting cis and -trans isomers.

But), which yielded [(OC)2(η-C5H4Me)Mn(µ-dppm)Pd(CNR)Cl2]. Reaction of the isocyanidecomplexes with azetidine did not lead to the expected carbene complexes, instead the isocyanide ligand was substituted by azetidine, yielding [(OC)2(η-C5H4Me)Mn(µ-dppm)Pd(NHC3H6)Cl2]. The structures of the xylylisocyanide and azetidine complexes have been determined by X ray diffraction. Reaction of [(OC)2(η-C5H4Me)Mn(µ-dppm)AuBr]
