Note: Strong oxidizing reagents will oxidize benzylic alcohols and carbonyls to carboxylic acids

Caution: Strong oxidizing reagents will oxidize benzylic alkyl groups even if no initial C-O bond exists

Caution: Even with extended alkyl chains, the strong oxidizing agent will wipe out all of the substituent chains down to benzylic carboxylic acids

Caution: Cr(IV) derived oxidizing reagents work to generate benzylic carboxylic acids as well. The difference is these are run under acidic conditions instead of basic

Note: Benzylic oxidation requires the presence of at least one benzylic hydrogen, so tert-butyl benzene is resistant to oxidation.

Note: Milder oxidant to oxidize benzylic alcohols to carbonyls

Note: Milder oxidant to oxidize benzylic alcohols to carbonyls

Note: Benzylic oxidation requires the presence of a benzylic hydrogen, so no reaction occurs here

Note: This reagent only works on benzylic alcohols, not 'regular' alkyl alcohols

Note: Clemmenen reduction converts aldehydes and ketones into alkanes under acidic conditions

Note: Wolff-Kishner reduction converts aldehydes and ketones into alkanes under basic conditions

Note: Nitro groups can be reduced to amino groups with H₂ and a metal catalyst

Note: Benzylic carbons can be brominated with NBS and peroxide, or Br₂ and light
