Bidentate Ru(II)‐NC Complexes as Catalysts for Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Recall from chapter 11 that carboxylates are not reactive in acyl substitution steps, so it follows that they cannot be directly reduced to aldehydes by an enzyme in the same way that thioesters can. Oxidative Transformations of Biosourced Alcohols Catalyzed by Earth-Abundant Transition Metals. The alcohol is always converted into the aldehyde, but sometimes the aldehydes that are formed cannot be further used in the body and are highly toxic. the Altmetric Attention Score and how the score is calculated.

Note that the same process with a primary alcohol would yield an aldehyde instead of a ketone. Many mechanistic patterns that we have already learned about in previous chapters will come into play again in this discussion, with the only variation being that here, a hydride ion will act as a nucleophile (in the hydrogenation direction) or as a leaving group (in the dehydrogenation direction).
