Epoxide to ketone using MgCl2

[PolytheneSam]

MgCl2 works as a  catalyst for converting epoxides to ketones.

Magnesium Chloride is significantly cheaper than Lithium Iodide - What is reference 47?

The Carlo Venturello patent above is the same as

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?

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...)

[PolytheneSam]

I'll have to check the book again.  Its at the library.

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:

Here's something which uses K or Na iodide and PEG.  MDP2P seems to be listed in table 1.

This looks interesting, too.

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?
