General description

Trovitch Mn-Precatalyst [((Ph2PPr)PDI)Mn] is a formally zerovalent manganese complex, containing phosphine-substituted PDI (pyridine diimine) ligand.[1][2] This hydrosilylation reagent can be synthesized by the reduction of (Ph2PPrPDI)MnCl2.[2] Its electronic structure has been studied.[2] Trovitch Mn-Precatalyst is also reported to mediate the dihydrosilylation of esters.[1][2]

Application

Mn-complex was commercialized in collaboration with Ryan Trovitch and coworkers. This complex has shown to be effective in the hydrosilylation of ketones and esters.

The Trovitch laboratory is working to develop first-row transition metal catalysts that can be used to achieve a variety of organic transformations. The first complexes from this group made available through Sigma-Aldrich are the hydrosilylation catalysts, (Ph2PPrPDI)Mn and (Ph2PPrDI)Ni. Although these compounds are formally zerovalent, both feature a reduced chelate that coordinates to the metal center beyond its redox non-innocent core.
