E) Hydroboration-oxidation of an internal alkyne. WebJul 18, 2002 · The onset of reduction occurs at ca. −1.9 V versus MMS and the current increases with increasing potential and can be attributed to the reduction of the aldehyde carbonyl group. In the reverse cycle, two re-oxidation processes are observed at ca. −0.58 V versus MMS and ca. −0.31 V versus MMS, respectively.
WebAldehydes and ketones can undergo reduction process for the formation of either primary alcohol or secondary alcohol with the help of reagents, sodium borohydride (NaBH 4) or lithium aluminium hydride (LiAlH 4 ). Aldehydes and ketones can also form alcohol by the process of catalytic hydrogenation.
