Manganese—lead bonds

Plumbyl halides with a lead-manganese bond have been prepared by the following dephenylation or demethylation reactions191 ... 

A hydroxy and an arylthio group can be added to a double bond by treatment with an aryl disulfide and lead tetraacetate in the presence of trifluoroacetic acid." Manganese and copper acetates have been used instead of Pb(OAc)4. ° Addition of the groups OH and RSO has been achieved by treatment of alkenes with O2 and a thiol (RSH)." Two RS groups were added, to give vie- dithiols, by treatment of the alkene with a disulfide RSSR and Bp3-etherate."° This reaction has been carried...

The complex can be viewed as a dimer of MnnMnm dimers joined by a single oxygen bridge, with the four manganese atoms assuming a chain disposition. It is interesting to note the presence of two coordinated water molecules (01), even if their positions at opposite ends prevent any possible mutual interaction to form an 0-0 bond able to lead to the development of dioxygen.
