The basicity of MeCN (1), MeNO2(2), and Et2NH (3) in the gas phase decreases in the series31>2, whereas the affinity of the same compounds for trimethylsilyl cation decreases in the series13≈2. Semiempirical quantum-chemical MNDO calculations indicate that the formation of MeCN·SiMe3+...
Reactivity of functional groups toward H+and SiMe3+ions On account of our interest in P4 activation by phosphenium ion insertion into P-P bonds we have developed synthetic routes to bicyclic N-P-Si-and probed its reactivity towards GaCl3 and P4. A GaCl3-induced rearrangement of leads to ...
We discuss the reactivity of 43 nucleophilic nitrogen compounds towards the nitroso group of N-methyl-N-nitrosotoluene-p-sulfonamide (MNTS), and in some cases with alkyl nitrites. The series of nucleophiles considered is structurally very varied, includes members exhibiting the alpha effect, and ...

Over the last 75 years, due to its high reactivity and peripheral cytotoxicity, numerous modifications have been made in the area of nitrogen mustard to improve its efficacy as well as enhancing drug delivery specifically to tumor cells. This review mainly discusses the medicinal chemistry aspects ...
(1993) developed a specific and sensitive assay which could be used to measure the amount of intracellular 1 gO2 produced in activated poly- morphonuclear leucocytes. Their method was based on the reactivity rates of 1 gO2 with perylene and 9,10-diphenylanthracene, and identifying the product ...
In a related study of potential precursors to novel B-N-P-N polymers, the preparation of a series of new phosphorus-(III) and -01) derivatives of the 1,3,2-diazaboracyclohexane ring system is described.关键词: organic chemistry, review organo‐boron compounds organo‐phosphorus compounds ...
These data partially explain the difference in reactivity observed between biological media and water during cold plasma treatment and their different biological activity with regards to cancer cells. Figure 11 Percentage of degradation of amino acids (0.2 mM) in water after He plasma treatment at...
5.1. Reactivity models - in non-aqueous systems The first chemical system found to reduce N2 was a non-aqueous mixture of titanium tetrachloride with a powerful reductant, such as ethylmagnesium bromide, in diethyl ether [137]. Although the reduction mechanism is unknown, this system likely clea...
