N-AcyloxyphthalimideSequential C−H functionalizationN‐Acyloxyphthalimide has been demonstrated as a multitasking directing group considering its easy accessibility, multiple reactive sites, and multifarious transformations available to generate valuable structural diversified scaffolds. Polysubstituted heterocycles,...
Recently, the visible-light photoredox decarboxylative couplings of N-(acyloxy)phthalimides (NHPI esters) and its derivatives have become an efficient chemical transformation. Under visible light, the NHPI esters undergo a single-electron transfer (SET) process to afford the corresponding carbon or nitr...

N-Acetoxy-phthalimide (NAPI) as a new H-abstracting agent at high temperature: application to the melt functionalization of polyethylene A new H-ing agent, N-acetoxy-phthalimide (NAPI), was designed that cleaves mainly homolytically into acyloxyl and aminyl radicals at 190 掳C. Melt PE graft...
This chapter describes the design and development of N-trifluoroacyloxyphthalimide as precursor to nitrogen-centered radical intermediates. N-trifluoroacyloxyphthalimide is proposed to undergo a single electron reduction by the photocatalyst ... P Cabrera Ventura 被引量: 0发表: 2017年 Solution thermodyn...

An improved, one-pot Minisci reaction has been developed using visible light, an organic photocatalyst and carboxylic acids as radical precursors via the intermediacy of in situ-generated N-(acyloxy)phthalimides. The conditions employed ... TC Sherwood,L Ning,AN Yazdani,... - 《Journal of Orga...
Derivatization of hydroxy groups as (acyloxy)methyl and (acyloxy)ethyl ethers, wherein the acyl group may be an alkyl ester, optionally substituted with one or more ether, amine, or carboxylic-acid functionalities, or where the acyl group is an amino acid ester as described above, is also ...
