Transesterification vs hydrolysis: the reactivity of metal-bound hydroxo moiety in [TPANi(II)(mu-OH)(2)Ni(II)TPA](ClO4)(2) (TPA = tris(2-pyridylmethyl)amine)
In the reaction of triphenyl phosphate with ethanol in the presence of complex 1, the transesterification to give diethyl phenyl phosphate was observed, in which system direct nucleophilic attack of ligated hydroxo moiety in 1 toward triphenyl phosphate also proceeded to give mu-phosphate complex, 2.
