of
caprolactone to
polycaprolactone by TBD. As a strong base, TBD fully
deprotonates most
phenols,
carboxylic acids, and some
carbon acids. It catalyzes a variety of reactions including
Michael reactions,
Henry reactions,
transesterification reactions, and
Knoevenagel condensations. Deprotonation at the 7-position gives a particularly
electron-rich ligand as manifested in the redox properties of
ditungsten tetra(hpp). The
conjugate acid of TBD is the preferred
cation among the
guanidinium hypoiodites, which are specialized
oxidizing agents for various types of
organic compounds. ==See also==
