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 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. This design element allows for ligand-centered electron storage with concomitant catalyst stabilization via the chelate effect. The manganese catalyst, (Ph2PPrPDI)Mn, exhibits outstanding carbonyl hydrosilylation activity at ambient temperature and has also been shown to reductively cleave the acyl C—O bonds of formates and esters. The nickel catalyst, (Ph2PPrDI)Ni, has been found to mediate the hydrosilylation of aldehydes, ketones, alkenes, alkynes, and ester C—O bonds. These catalysts are air and water sensitive and should be handled under inert atmosphere. More information regarding the performance of these catalysts is available through the links provided below.
