Stoichiometric and Catalytic Reactivity of 2-Rhodacyclobutanes

Principal Investigator: 
Research Area(s): 

The investigation of the reactivity of 2-rhodaoxetanes is underway. We anticipate that these species can serve as intermediates in catalytic alkene carbohydroxylation and aminohydroxylation. Toward this end, we have demonstrated that a rhodium (III) oxetane, obtained in one step from a rhodium(I)-ethylene complex, readily reacts with a series of organometallic reagents to generate ring-opened products [Dauth, A; Love, J. A. “Stoichiometric and Catalytic Reactions of 2-Rhodaoxetanes,” project underway]. We are now exploring the feasibility of reductive elimination. If successful, this process would permit the facile functionalization of ethylene.
