Collision-induced loss of AgH from Ag<sup>+</sup>adducts of alkylamines, aminocarboxylic acids and alkyl benzyl ethers leads exclusively to thermodynamically favored product ions
α‐methylene group carrying the nitrogen function (formation of an immonium ion). In all cases examined, the most stable, i.e. the thermodynamically favored product ion is formed. In the AgH loss process, a large isotope effect operates discriminating against the loss of D. The [M + Ag]+ ion of benzyl methyl ether loses a hydride ion exclusively from the benzylic methylene group supporting the experimental

Permanganate, solubilized in methylene chloride with the aid of a phase transfer agent, oxidizes benzyl alcohol to benzaldehyde and benzyl ethers to benzoate esters. Although the rate of oxidation of the ether is about an order of magnitude slower than alcohol oxidation, both respond in an identical way to the unique effects caused by introduction of substituents into the ring. In addition, primary
