Greetngs to all ,

I am looking for procedures for the formylation (primarily) orchloromethylation (secondarily) of the symmetric 1,4-diiodobenzene.Essentially I am trying to prepare1,4-diiodobenzaldehyde or 1,4-diiodobenzylalcohol. If there is anyoneout that has experience with either formylation, carbonylation, orchloromethylation of 1,4-dihalobenzenes, I would greatly appreciatedany advice, input, or literature references.

If someone has another reasonablyshort or direct route to synthesize 1,4-diiodobenzylalcohol
I would be interested in considering that as well. Our Current route israther long ,tedious, and does not lend well to scale up.

Thank you in advance to all my fellow chemists!

Brad
