For 10 points, name this type of reaction often paired with a reduction reaction.
One reaction of this type uses oxalyl chloride and DMSO, and another uses mCPBA to convert ketones to esters. PCC is used in some reactions of this type, examples of which include the Swern and Baeyer-Villiger reactions. This type of reaction cannot happen to a tertiary alcohol, but can convert a primary alcohol to an aldehyde or a secondary alcohol to a ketone. Half-reactions describing this process include electrons on the right-hand side. It is defined as the loss of electrons or an increase in its namesake state. For 10 points, name this type of reaction often paired with a reduction reaction.
