Abstract
An open-shell polyoxopalladate(II), TBA-Na-SrPd12(pent)3 (TBA = [(n-C4H9)4N]+, pent = [C5H9O2]-), was used as catalyst in the hydration of aromatic nitrile for the first time, because such structure exhibits ligand exchange ability. TBA-Na-SrPd12(pent)3 has been proven to be active for a series of substrates and interestingly the yield (22% ∼ 98%) is significantly influenced by the steric hindrance of aromatic nitriles. Furthermore, this polyoxopalladate can promote the hydration of benzonitrile under solvent-free conditions giving the yield of 99%.
