How to make chromium ethoxide?
I am beginning to discover the magic of organometallic compounds and the CVD method,but I have hardly been involved in organic chemistry so
far.According to Google,aluminium ethoxide is relatively easy to produce by reacting aluminium with anhydrous ethanol in the presence of gallium,from
an aluminium-gallium alloy.I just can't think how to produce its chromium analogue?I have searched the internet,but I haven't found any specific
advice.Is there any easy way to do this?Thanks.

Not an organic chemistry expert, but I doubt that Cr ethoxide would be possible to make. Al is way more reactive than Cr. And how do you want to
remove oxide layer from Cr?

Maybe if you can get CrH2 to react with ethanol. But CrH2 tends to polymerize, so it might be unreactive like CuH2

It was clear to me that you can't use the same reaction as with aluminum, for this very reason, otherwise I wouldn't have asked and do tried it:-)I
read that chromium ethoxide is used as a precursor to other advanced chemical syntheses in organic chemistry.So there must be some way to synthesize
it...I'm sure someone in our community will know, there are undoubtedly some great organic chemists among us;-)
