Triazabicyclodecene (1,5,7-Triazabicyclo[4.4.0]dec-5-ene or TBD) is a commercially available bicyclic strong guanidine base (pKa=25.98 in CH3CN and pKa=21.00 in THF). TBD is an organic soluble base which has been used effectively for a variety of base-mediated organic transformations such as: Michael reactions, Henry (nitroaldol reactions), Wittig reactions, HornerWadsworthEmmons reactions, transesterification reactions, etherifications, ring-opening polymerizations (Scheme 1), tautomerizations and epimerizations PC and PN bond formations, Knoevenagel condensations, deprotonation reactions of phenols, carboxylic acids and C-acids (Scheme 2), aminolysis of esters. It is also known in deprotonated form (at the 7-position), often as a ligand, for instance in Ditungsten tetra(hpp)
