Fusing two carbon chain

Blind Angel - 8-3-2003 at 17:34

Just by curiositie, is there a way to fuse two carbon chain. Like merging two Methanol which would yield 1,2-ethanediol or anything like that, i've looked for bromination but for this i would need to get rid of the hydroxy and would yield only ethane. I also thought of a grignar regeant but the result would be the same.

Is there another way (single step or multi step) to this formula:
2CH<sub>3</sub>CHOH => OHCH<sub>2</sub>CH<sub>2</sub>OH + H<sub>2</sub>
or
CH<sub>3</sub>OH + CHOOH => COOHCH<sub>2</sub>OH
?

Exmple
CH3CH2Br + CH3CH2CH2MgBr > CH3CH2CH2CH2CH3

=alkylation

There are many opportunities.....just have a look at

(that´s just one good reference....there are thousands around the web....)

I already though of that (grignard regeant and bromination) but what about if i want to keep the -OH or -OOH group in the molecule. I looked on the site and every reaction break these group. If they're is a way to add a -OH group on the two side of the chain (double oxydation would yield more a carboxylic acid) or one side a -OH and on the other side a -OOH (triple oxidation would yield an ester), this is why i though of fusing two molecule...

I was thinking of something along those lines for making diamonds, im sure it wont work but i am wondering why? If i take pentane that has 4 methyl groups of a center carbon how could i posibly replase each methyl group with another penatane and keep i going?
