Bis(tetrabutylammonium) dichromate Chemical Properties,Usage,Production

Uses

Reagent for:

Preparation of nitrophenol derivatives and quinones under aprotic reaction conditions
Conversion of oximes to carbonyl compounds under microwave irradiation

Catalyst precursor for catalytic gas phase dehydration of acetic acid to ketene
Crosslinking agent

Application

Bis(tetrabutylammonium) Dichromate (TBADC) is a mild selective oxidizing agent for benzylic and allylic alcohols^[1]. It can oxidize carbon-halogen bonds^[2].

Preparation

Preparative Method of Bis(tetrabutylammonium) Dichromate (TBADC): a concentrated aqueous solution (300 mL) of Potassium Dichromate (29.4 g, 0.1 mol) is added to a saturated aqueous solution (300 mL) of Tetra-n-butylammonium Bromide (64.4 g, 0.2 mol). TBADC precipitates and can be removed by filtration (62.8 g, 90% yield).

reaction suitability

reagent type: oxidant

storage

Bis(tetrabutylammonium) dichromate was reported to be a toxic agent. The reagent should be handled in a fume hood.

Purification Methods

Wash it with water and dry it in a vacuum. Recrystallise it from hexane (m 79-80o). [Santaniello & Ferraboschi Synth Commun 10 75 1980, Beilstein 4 IV 556.] (Possible CARCINOGEN.)
