- Radical Addition of Silanes to Alkenes Followed by Oxidation
[作者:PALFRAMAN MATTHEW J; PARSONS ANDREW F; JOHNSON PAUL,期刊:SYNLETT, 页码:2811-2814 , 文章类型: Article,,卷期:2011年-19]
- Phenyldimethylsilane and trichlorosilane are shown to undergo efficient radical hydrosilylation reactions, on reaction with various alkenes, using triethylborane as the initiator. Adducts from the trichlorosilane reactio...
- Phosphomolybdic Acid Catalyzed Synthesis of 1,2,4,5-Tetraoxanes
[作者:YAN XING; CHEN JINGLEI; ZHU YUNTING; QIAO CHUNHUA,期刊:SYNLETT, 页码:2827-2830 , 文章类型: Article,,卷期:2011年-19]
- 1,1-Dihydroperoxides were converted into 1,2,4,5-tetraoxanes through condensation with the corresponding ketones in 36-91% yields using phosphomolybdic acid as the catalyst and anhydrous MgSO(4) as the water scavenger.
- Easy Access to (E)-beta-Ocimene
[作者:YILDIZHAN SELMA; SCHULZ STEFAN,期刊:SYNLETT, 页码:2831-2833 , 文章类型: Article,,卷期:2011年-19]
- beta-Ocimene is one of the most common monoterpenes found in Nature, but a simple and reliable synthesis of the pure E-isomer has been missing. Here, we report a simple procedure involving a Grignard coupling as the key ...
