What is TBD (triazabicyclodecene)?

Triazabicyclodecene (1,5,7-Triazabicyclo[4.4.0]dec-5-ene or TBD) is a commercially available bicyclic strong guanidine base (pK a = 25.98 in CH 3CN and pK a = 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:

What is the standard temperature of triazabicyclodecene?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).?) Triazabicyclodecene ( 1,5,7-triazabicyclo [4.4.0]dec-5-ene or TBD) is a commercially available bicyclic strong guanidine base (p Ka = 25.98 in CH 3 CN and p Ka = 21.00 in THF ).

What is TBD used for in caprolactone polymerization?

Caprolactone polymerization. TBD is used as a catalyst in the ring opening polymerization of caprolactone to polycaprolactone. TBD acts as a bifunctional catalyst with simultaneous acyl transfer and hydrogen bonding. Scheme 2.
