Di-tert-butyl chromate is an alkoxide with the formula CrO2(OC(CH3)3)2.

It is prepared by treatment of t-butanol with chromic anhydride.

[3][4] The complex, which is diamagnetic, is of fundamental interest as a model for the intermediates in oxidations of alcohols by chromium(VI).

This complex is stable because as a t-butyl groups lack beta-hydrogens.

[7] Like other forms of hexavalent chromium, di-tert-butyl chromate is classified as a potential carcinogen by the United States National Institute for Occupational Safety and Health.
