ACTIVATION OF AMMONIA, SECONDARY, AND TERTIARY AMINES BY GROUP IIA AND FIRST ROW MIDDLE AND LATE TRANSITION METAL ATOMS AND CLUSTERS
Activation of ammonia and amines occurs during metal vapor synthesis at cryogenic temperatures. The Group IIA metal atoms: magnesium, calcium, strontium, and barium, and the transition metal atoms: chromium, manganese, iron, cobalt, nickel, and zinc react with amines and ammonia. Copper metal atoms …

Syntheses, structures and properties of novel poly(amino ester)s
… Michael addition polymerization of trifunctional amines and diacrylates or triacrylates were clearly clarified. Based on the results, we designed and synthesized two novel kinds of poly(amino ester)s, i.e., linear poly(amino ester)s with secondary and tertiary amines in their backbones and …

A novel photocatalytic strategy for complex aliphatic amine synthesis and the total synthesis of alkaloids (−) FR901483 and (+)-TAN1251C
… the synthesis and functionalization of aliphatic amines plays a central role in the field of visible light photoredox chemistry. In this thesis, the development of a novel, visible light mediated process for the synthesis of complex aliphatic amines is described. The novel multicomponent reaction …

Radical methods for the synthesis of aliphatic amines
… radical reactions for the synthesis of aliphatic amines. Following an introduction to radical chemistry and a summary of previous advances in amine synthesis, chapter 2 will describe a general carbonyl alkylative amination reaction, a successful version of which has been sought for over 70 years. …

Toxicity of aliphatic amines on the embryos of zebrafish Danio rerio - experimental studies and QSAR
The toxicity of 36 aliphatic amines on the embryos of the zebrafish Danio rerio were investigated. The DarT (Danio rerio Toxicity assay) was used to determine the lethal concentrations within a 48 h static acute toxicity test. A QSAR (Quantitative Structure-Activity Relationship) was performed …

Preparation and properties of N-pentafluorosulfanylamido derivatives
… The malonamide was found to decompose with tertiary amines such as pyridine. Attempts to react the malonamide with carbonyl chloride, fluoride, and sulfide to form a barbiturate were unsuccessful. N-Phenyl-N’-pentafluorosulfanyl was prepared from pentafluorosulfanyl isocyanate and aniline. …
