The Kinetics and Mechanism of the Acid-Catalyzed Reaction of Diphenyldiazomethane with Ethyl Alcohol^1,2

Synthesis of novel macromonomers and telechelics of poly(2‐alkyl‐2‐oxazoline)s

“…The telechelic polymer 15 was converted quantitatively to the corre-sponding bis(benzhydry1 ester) 16 by treatment with PhCN2. 36 The molecular weights of 15 in Table IV were derived from those of 16 measured by GPC. The functionality of 15 was determined by comparison of the signal integration values of phenyl protons a t 7 ppm and N-methyl protons a t 2.96 ppm in the 'H NMR spectrum of 16.…”

Straightforward Synthesis of Ethers: Metal‐Free Reductive Coupling of Tosylhydrazones with Alcohols or Phenols

“…[11] Although many OÀH insertion processes with phenols have been reported before, most of the examples involve diazo compounds stabilized by electron-withdrawing groups such as diazo ketones or diazo esters. [12,13] Moreover, the majority of the transformations are acid- [14] or transitionmetal-catalyzed reactions, [15] as well as photochemical transformations. [16] Additionally, the thermal decomposition of diazo compounds in the presence of alcohols is extremely rare.…”
