A type of reaction of unsaturated hydrocarbons with hydrogen, halogens, halogen acids, and other reagents, so that no change in valency is observed and the organic compound forms a more complex one.McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hi...
Comparison with H atom data reveals (1) appreciable kinetic isotope effects, (2) a strong contribution of tunnelling for the activated reaction with benzene, (3) encounter controlled reaction for Mu addition to the diene, (4) a mass dependence of the diffusion constant of hydrogen isotopes in ...

Alternatively, aza-Michael additions can be used to create carbon-heteroatom bonds by reaction of a,a-unsaturated carbonyl compounds with amines. Although ... XIA Chun-Gu XU,Li-Wen - 《合成化学》 被引量: 33发表: 2004年 Chemical effects of acoustic cavitation A novel high-frequency, high-pow...
该中间体受热脱水和水解得到不饱和羧酸 The acetic anhydride loses the hydrogen atom under the alkali function, the production acetic anhydride anoin, this anoin and the benzene has the nucleophilic addition reaction to obtain the carboxyl group acid anhydride intermediate, this intermediate being heated...
·Et2O. We found that the hydrogen on thetrans-olefins formed (C13H) was from the added acid. Deuterated phenylacetylene was also tested in the reaction, and as expected, the hydrogen atom of terminal alkyne of phenylacetylene was not involved in the reaction. The identifications of3-d1and3...
In the templated hexakis-addition reaction of malonic esters with C(60) to prepare dendritic macromolecules that are terminated symmetrically with 12 derivatized pyrenes, a simple modification to use a much larger excess of the bromination agent resulted in dramatic increases in the product yields. ...

1. Addition of Hydrogen Halides To Alkynes (Once) – Hydrohalogenation The three major examples in this category are the reaction of hydrohalic acids (H-Cl, H-Br, and H-I) with alkynes. If you recall, when added to alkenes, these reagents were: ...
