TLDR
Rate constants for the reaction of phosphate radical with some aromatic and aliphatic amines have been determined by the flash photolysis technique and the products formed under conditions of continuous irradiation have been identified.Abstract:
Rate constants for the reaction of phosphate radical with some aromatic and aliphatic amines have been determined by the flash photolysis technique. The products formed under conditions of continuous irradiation have been identified. In the case of an aromatic amine the major product is the azo compound while in the case of an aliphatic amine a carbonyl compound is formed.read more

Structure–Activity Relationships for Rates of Aromatic Amine Oxidation by Manganese Dioxide
TL;DR: A training set of new and previously reported kinetic data for the oxidation of model and energetic-derived aromatic amines was assembled and subjected to correlation analysis against descriptor variables that ranged from general purpose to specific for the likely rate-limiting step of one-electron oxidation potentials (Eox).

Photochemical formation of singlet molecular oxygen (1O2) in illuminated aqueous solutions of p-aminobenzoic acid (PABA)
TL;DR: Significant evidence is presented for the photochemical formation of singlet molecular oxygen (1O2) in air-saturated buffered aqueous solutions of p-aminobenzoic acid (PABA) using sunlight-range illumination because PABA is widely used as an active ingredient in sunscreen preparations that are applied to the surface of the skin.
Journal ArticleDOI
The photochemistry of p-aminobenzoic acid.
TL;DR: Studies of the thermal oxidation of I, coupled with evidence gathered from studies of the photochemistry of incompletely deoxygenated PABA solutions, indicate that 4‐(2,5‐cyclohexadien‐4‐one)iminobenzoic acid (III) is an intermediate on the pathway between I and IV.

PHOTOADDITION OF p‐AMINOBENZOIC ACID TO THYMINE AND THYMIDINE
TL;DR: The isolation and characterization of thymine‐PA BA and thymidine‐PABA photoadducts are reported and these products have been identified, respectively, as 5‐(2‐amino‐5‐carboxyphenyl)‐5,6‐dihydrothymine and isomeric forms of 5‐ (2‐amsino‐ 5‐car boxyphenol)‐ 5, 6‐dhydrothymidine.
Fully in Silico Calibration of Empirical Predictive Models for Environmental Fate Properties of Novel Munitions Compounds
TL;DR: This work used a hybrid, partially in silico approach to QSAR development, where some of the calibration data (both the target variable and the descriptor variables) were calculated from molecular structure theory.
