The Chemistry of Diisopropyl Chromate

Kinetics and mechanism of the oxidation of alcohols by ruthenate and perruthenate ions

“…2-Propanol-2-d was prepared following the procedure of Leo and Westheimer (12). Dry acetone (86 mmol) in 20 mL of anhydrous ether was added dropwise to a stirred solution of lithium aluminum deuteride (25 mmol) in 50 mL of anhydrous ether at -80°C.…”

“…OH Addition to an 0-H bond (as in reaction [12]) leads to formation of esters, intermediates that have been proposed for several reactions, the most well known being the oxidation of alcohols by chromic acid (25).…”

“…Fortunately it is possible to experimentally distinguish between the possibilities shown in reactions [12] and [13]. If a reaction occurs by addition to an 0-H bond it is expected that the oxidant would not react as readily with ethers as with alcohols.…”

Esters chromiques dérivés du tertiobutanol

“…(iii) L'hydrolyse du chromate 1 est facile (8). En effet, dans le cas dc l'ester 1, le caractkre hydrophobe serait rtduit comparativement aux autres esters chromiques dtrivts d'alcools tertiaires aliphatiques hydrocarbonks qui renferinent des chaines hydrocarbone'es plus Iongues.…”
