Abstract

Synthesis of a trifluoroacetate-bridged tetranuclear zinc cluster and its trifluoroacetic acid (TFA) adduct under mild conditions (∼110 °C) was achieved. The catalytic activity and functional group tolerance of the TFA adduct in transesterification and oxazoline formation were almost identical to those of the original zinc cluster.
