# Elimination of bromide and acetate under reducing conditions

Here is the reaction that I didn't find the mechanism of:

• The conditions are zinc dust, acetic acid (solvent) at $$\pu{11 °C}$$ for 1 h.

• The reagents are sodium acetate; 2,3,4,5-tetraacetoxy-1,6-bromohexane.

• There is also some evolution of gas (I don't know what it is, $$\ce{HBr}$$ or $$\ce{CO2}$$).

What reaction can lead to this elimination when it seems that no proton is leaving the molecule (instead of bromide) and acetate is leaving?

• Pardon me? I edited your Q but it seems that there are little typos you got there. Did you really use Actinium Hydroxide as your solvent?! Even if you did so, formula shouldn't be AcOH; am I wrong? Dec 27 '14 at 13:55
• i meant an acetic acid sorry
