Abstract

[Re(CH3CN)3Br2(NO)] catalyzes the homogeneous hydrosilylation of a great variety of organic carbonyl compounds (ketones and aldehydes). The reaction is quite sensitive to the solvent applied. CH2Cl2, Dioxane, THF, CH3CN, DMF, Benzene, DMSO, tolu-ene and chlorobenzene were probed. Chlorobenzene was found to be superior over all the other solvents applied. Various silanes, like HSiEt3, PhSiH3, Ph2MeSiH, PhMe2SiH, (i-Pr)3SiH, (n-Bu)3SiH, Ph2SiH2, HSi(OMe)3, PMHS and HSi(SiMe3)3 were tested. Excellent yields were achieved at 85 oC in chlorobenzene using triethylsilane affording TOF values of up to 495 h-

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
