Tetrakis(tetrabutylammonium) decatungstate (TBADT) is an organic solvent-soluble polyoxometalate compound that can act as a C-H abstraction catalyst under UV-activated conditions.

It can promote the generation of carbon radicals from otherwise stable tertiary and secondary C-H bonds. The functionalization of C(sp3)-H bonds is possible by trapping the radicals by suitable reagents.

TBADT is drawing an attention as a useful catalyst for C-H activation, the rapidly-growing subfield of organic chemistry.
