Zinc / HCl reduction


Does anyone know the exact reaction conditions ( proportion of reactants, conc of acid, eq of Zn, etc ) and especially yields for the above to reduce an aliphatic primary halide ( R-Cl ) to its alkane ?
Though there is a lot of mention of this reaction on the web, there are absolutely no detailed reaction conditions given anywhere. Have checked far and wide, just got one ref that gave a measly yield of 12%.
How about using Aluminum with acid for such reductions ? There is no mention of this anywhere.......

I know the zinc-copper couple will do it, but I've never heard of just plain zinc being used.



As below, so above.

Read the thread about nascent hydrogen here. Ig will give you few answers on mechanisms.
