some ideas on otc benzene and a few q's on amalgum | Bookmark | ||||||
well I have been doing more reserch on demethylation of toluene to benzene and I now strongly belive that the CaO will not work (yes I have been told this on the hive) I belive that if doing a decarbox on benzoic acid you will leave behind a ketal group where your origonal methyl group was. so what can you do with benzene with a ketal group on it. well I belive you can put it through a Zinc/Hg amalgum with HCl hopfully adding H to the ketal making it into OH then ripping it off to form a methylene group on the carbon that was linked to the ketal group well some Q's now. benzene doesnt realy have any methylene groups. as far as I know it has a wierd hydrogen sharing system going. where instead of having H all over it it has half as much and rotates the hydrogen around the outside of the ring. well if we dont realy have methylene's in benzene will the zinc amalgum fuck up the resonance of the ring. if it does am I likly to see a compound with a higher boiling point than benzene or very simular. Al/Hg gives off H and so does Mg/Hg can I use these instead of zinc. is it possible to use Zinc and magnesium for amalgums with nitro and methylamine reductive aminations. are there any other metals that will amalgumate like these three? anyway thanx again guys e3500 console login: root bash-2.05# |

I belive that if doing a decarbox on benzoic acid you will leave behind a ketal group where your origonal methyl group was. Decarboxylating benzoic acid will give you benzene directly. No ketal. However, benzoic acid has no methyl groups to begin with, so I don't know if you really understand what you are asking... |
