A mass spectrometric method is presented that facilitates the identification and differentiation of primary, secondary and tertiary amino functionalities in protonated monofunctional analytes. This method utilizes gas-phase ion-molecule reactions of protonated analytes with neutral hexamethylphosphoramide (HMPA) and diethylmethylphosphonate (DEMP) in a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR). A variety of protonated analytes containing different functional groups, namely, amino, amido, N-oxide and various oxygen-containing functional groups, were examined to demonstrate that protonated primary and secondary amines can be identified and differentiated by reactions with HMPA and DEMP. However, differentiation of tertiary amines from some N-oxides requires additional experiments. First, protonated secondary and tertiary amines can be differentiated from protonated primary amines, amides and oxygen-containing functionalities, as well as from each other (but not from protonated N-oxides), by using HMPA. Protonated primary amines, amides, some N-oxides and oxygen-containing analytes, most with a proton affinity (PA) < 229 kcal/mol, only transfer a proton to HMPA (PA = 229 kcal/mol). In contrast, protonated secondary amines also form two stable hydrogen-bound adducts (MH+ + HMPA, MH+ + 2HMPA; M: amine), and tertiary amines and some N-oxides (with PA ? 222 kcal/mol) react with HMPA by forming just one stable hydrogen-bound adduct (MH+ + HMPA). Further, ion-molecule reactions with the other reagent, DEMP, allow the differentiation of protonated primary and secondary amines from tertiary amines and N-oxides and from protonated oxygen-containing analytes and amides. Protonated primary amines and secondary amines (most with PA ? 220 kcal/mol) react with DEMP (PA = 219 kcal/mol) by forming two stable hydrogen-bound adducts (MH+ + DEMP and MH+ + 2DEMP), while protonated oxygen-containing analytes and amides (with PA ? 221 kcal/mol) solely transfer a proton to DEMP. Protonated tertiary amines and N-oxides react yet differently, and yield only one stable hydrogen-bound adduct (MH+ + DEMP) with DEMP. Protonated N-oxides can be differentiated from protonated tertiary amines by using previously reported methods based on diagnostic ion-molecule reactions of protonated N-oxides with 2-methoxypropene, dimethyl disulfide and/or tri(dimethylamine)borane.

A few N-alkoxypyridinium salts are developed as photoinitiators for efficient polymerization reactions. They are characterized by absorption properties below 300 nm, and generate alkoxy radicals on UV-Vis light exposure. The squarylium dye was used as a blue-light photosensitizer. Polymerization results are correlated with the photochemistry of N-alkoxypyridinium salts. The quenching of the excited singlet state of squarylium dye by pyridinium salt and the formation of the semioxidized species of squaraine suggests an electron transfer from an excited dye to a coinitiator, and that the resulting oxygen-centered radical initiates the polymerization process. The chemical mechanism was investigated by steady state photolysis and nanosecond laser flash photolysis experiments. Photoinitiating activity of new photoinitiators for initiation of polymerization of trimethylolpropane triacrylate in the UV-blue light region was compared with photoinitiating ability of selected commercially available initiators.

A simple and efficient method for the deoxygenation of amine N-oxides to corresponding amines is reported using the green and economical reagent phenylboronic acid. Deoxygenation of N,N-dialkylaniline N-oxides, trialkylamine N-oxides and pyridine N-oxides were achieved in good to excellent yields. The reduction susceptible functional groups such as ketone, amide, ester and nitro groups are well tolerated with phenylboronic acid during the deoxygenation process even at high temperature. In addition, an indirect method for identification and quantification of tert-amine N-oxide is demonstrated using UV?Vis spectrometry which may be useful for drug metabolism studies.

A formal [3+2] cycloaddition of N-aryl alpha-amino acids with isoquinoline N-oxides via visible light-driven photoredox catalysis is reported. Under transition metal-free conditions using a dicyanopyrazine-derived chromophore (DPZ) as the photoredox catalyst, the transformation was efficient and led to a series of important diazabicyclo[3.2.1]octane-based N-heterocyclic compounds. This work demonstrates the synthetic utility of N-aryl alpha-amino acids as 1,2-synthons and provides a new strategy for the dearomatization of isoquinolines.

The metal-free reactions of 1,4-diynes and 1-en-4-yn-3-ones with isoquinoline and quinoline N-oxides are developed, resulting in the formation of 3,4-dihydro-2H-pyrido[2,1-a]isoquinolines and 2,3-dihydro-1H-pyrido[1,2-a]quinolines via cascade C=O/C=C/C-N bond formation. It is the first report in which in the alkyne oxidation by N-oxides both the oxygen atom of N-oxides and the nitrogen atom are involved in a second C-heteroatom bond formation. The reactions showed a broad substrate scope and functional group tolerance. Furthermore, the products were found to display green-blue fluorescence in DMSO with fluorescence quantum yields up to 0.59.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: isoquinoline, you can also check out more blogs about1532-72-5

Pyridine-N-oxides are often used as reactive precursors in the syntheses of substituted pyridines. Isolation and subsequent reduction of the associated pyridine-N-oxide intermediates can be challenging. We have discovered that tetrahydroxydiboron functions as a mild, versatile, and remarkably selective reducing agent for pyridine-N-oxides and may be used in an in situ fashion, thus obviating the isolation of N-oxide-containing intermediates.
