Di-tert-butyl chromate
Chemical compound
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. It forms red crystals at temperatures below –5 °C, above which it melts to give a red oil.[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. This complex and its analogues have tetrahedral geometry at chromium, as established by X-ray crystallography of its analogues.[5][6]
