Electrochemical Synthesis of N,O‐Dialkylarylhydroxylamines and N,O‐Diacylarylhydroxylamines

“…[1], for temperatures below a transition temperature, and by Eq. Moreover, when using these equations it is generally assumed that complete dissociation of the ions occured, even though this condition does not always apply (9,10,(13)(14)(15). These equations do not yield in any way to the mechanisms governing ionic conductivity in polymer electrolytes, although analysis of the characteristic parameters (Ea, eo, To and A) obtained from these equations can serve as a basis for formulating assumptions.…”

“…Several reports describe 1,3 sigmatropic shifts of activated groups, such as allyl and benzyl, from nitrogen to oxygen of amine oxides (2)(3)(4)(5)(6)(7)(8)(9). The addition of alkyl radials to aromatic nitrosocompounds (15)(16)(17), or nitrones (18)(19), has been used to prepare N,O-dialkylarylhydroxylamines. The addition of alkyl radials to aromatic nitrosocompounds (15)(16)(17), or nitrones (18)(19), has been used to prepare N,O-dialkylarylhydroxylamines.…”

“…Another general scheme involves treatment of an N-alkyl or O-alkyl arylhydroxylamine with base and an alkylating agent to attach the second alkyl group (10)(11)(12)(13)(14). The addition of alkyl radials to aromatic nitrosocompounds (15)(16)(17), or nitrones (18)(19), has been used to prepare N,O-dialkylarylhydroxylamines. Similarly, trialkylhydroxylamines have been prepared by reaction of alkyl nitroso compounds with alkyl radicals (20).…”
