The aim of this tutorial reviewis to point out the most recent advances in this field and to encourage the use of this reaction enroute to complex molecules. After summarizing the most common catalysts and reaction conditions generally used, we survey the mechanistic features currently accepted ...
“We use rhodium nanotips that behave like nanoparticles,” says Günther Rupprechter. “They can serve as catalysts, for example, when hydrogen and oxygen are combined to form water molecules – the reaction we are examining in detail.” ...
Use of supported catalysts in transformation reactions of organic compounds The catalyst is prepared from a colloid suspension of a metal oxide which is then deposited on a support and reduced to metal. By this means an increased a... PC Carine,D Blaise,U Denis - EP 被引量: 251发表: 2008...
This review deals with reactions of tertiary silanes R 3 SiH with unsaturated organic compounds (e.g. alkanes, dienes, alkynes, ketones, and aldehydes) and with alcohols R'OH, using transition- metal complexes as catalysts. Due to the bulk of relevant literature, special attention has been giv...
