Kevin W C Poon et al.
The Journal of organic chemistry, 71(10), 3923-3927 (2006-05-06)
2-Benzyloxy-1-methylpyridinium triflate (1) is a stable, neutral organic salt that converts alcohols into benzyl ethers upon warming. The synthesis and reactivity of 1 are described herein. Benzylation of a wide range of alcohols occurs in good to excellent yield.
Jumreang Tummatorn et al.
The Journal of organic chemistry, 72(23), 8962-8964 (2007-10-16)
Triethylamine (Et3N) mediates esterification reactions between the title reagent (1) and carboxylic acids. Alcohols, phenols, amides, and other sensitive functionality are not affected; a dual role for Et3N as a promoter and a scavenger is postulated. Benzyl esters are obtained

Dudley Benzylation Reagent

Benzyl ethers and derivatives are among the most widely used protecting groups in organic synthesis. Cleavage can be effected under a variety of conditions including hydrogenolysis, oxidation, and acid decomposition.

Dudley Benzylation Reagent

Benzyl ethers and derivatives are among the most widely used protecting groups in organic synthesis. Cleavage can be effected under a variety of conditions including hydrogenolysis, oxidation, and acid decomposition.

Dudley Reagents

Benzyl and p-methoxy benzyl protecting groups require use of acidic or basic reaction media and/or otherwise non-mild reaction conditions, which sometimes are not compatible with other functional groups in the molecule. Dudley Reagents provide protection of alcohols and carboxylic acids under relatively neutral reaction conditions
