Epoxide to ketone using MgCl2 | Bookmark | ||||||
MgCl2 works as a catalyst for converting epoxides to ketones. from Mono-Olefins, Chemistry and Technology by F. Asinger 1968 see also Patent US4731482 http://www.geocities.com/dritte123/PSPF. The hardest thing to explain is the obvious |

Magnesium Chloride is significantly cheaper than Lithium Iodide - What is reference 47? The Carlo Venturello patent above is the same as ../rhodium /peroxot |

more available too | Bookmark | ||||||
A quick search on google shows that MgCl2 hexahydrate seems to have a few OTC sources. |

47 refers to H. Koch & H. Van Ray, Brennst.-Chemie 32, 161-74 (1951) What is Brennst.-Chemie? http://www.geocities.com/dritte123/PSPF. The hardest thing to explain is the obvious |

ref? | Bookmark | ||||||
sam: are you sure that this is the right reference? i had a look through the article (provided by lugh), but i couldn't find anything about acetone or magnesium halides. the whole article is about isomerisation equilibria of hexenes. (possible that i fell asleep during reading the thing, the topic wasn't all too exciting...) |

It appears that 47 refers to DE 1119246 and Chem. Abstr. 57, 7176i (1962) Patent DE1119246 I must have looked at the end of the wrong chapter the last time. From espacenet this appears to be the British equivalent: Patent GB905821 http://www.geocities.com/dritte123/PSPF. The hardest thing to explain is the obvious |

US 4734529 etc. | Bookmark | ||||||
Here's something which uses K or Na iodide and PEG. MDP2P seems to be listed in table 1. Patent US4734529 This looks interesting, too. Patent US3935272 olefins to epoxides and ketones http://www.geocities.com/dritte123/PSPF. The hardest thing to explain is the obvious |

Very interesting. They say that safrole-epoxide ... | Bookmark | ||||||
Very interesting. They say that safrole-epoxide can be isomerised to MDP2P with NaI/PEG in 80-90% conversion. Yield of end product, at least for isosafrol epoxide is lower however. Maybe it could be improved? I'm not fat just horizontally disproportionate. |
