Usage

Characteristics

Inexpensive UV absorber with good performance, but tends to turn yellow when exposed to light. 4-tert-Butylphenyl Salicylate can be used in PVC, polyethylene, cellulosic plastics and polyurethane. The addition amount is 0.2-1.5 parts.

Uses

Food additive.

Hazard

Moderately toxic by ingestion.

Synthesis

4-tert-Butylphenyl Salicylate is obtained by reacting salicylic acid with 4-tert-butylphenol with phosphorus oxychloride.

N-Heterocyclic carbene/photo-cocatalyzed oxidative Smiles rearrangement: Synthesis of aryl salicylates from: O -aryl salicylaldehydes

The N-heterocyclic carbene/photo-cocatalyzed oxidative Smiles rearrangement of O-aryl salicylaldehydes was developed. Both electron-deficient and electron-rich aryls worked well as migrating groups, giving the corresponding aryl salicylates in good yields. This reaction features formation of two new C-O bonds and one C-O bond cleavage via metal-free oxidation of the Breslow intermediate using oxygen as the terminal oxidant and following the Smiles rearrangement under photocatalysis.
