Diiodomethyl iodid

Cleavage of ethers and ketals. Hydrogen iodide in acetonitrile, generated from Nal and diiodomethyl methyl ether, is an effective reagent for cleavage of primary and secondary alkyl methyl ethers (20", 30 minutes). Hydrogen iodide generated from Nal and T.sOH is. somewhat less reactive. In other solvent.s, HI... 

The diiodomethylation of carbonyl compounds is also possible if samarium iodide is used in conjunction with iodoform. The products are synthetically useful since they are easily converted into or-hydroxyacids or a-iodoaldehydes upon basic treatment (eq 49).

Iodine is stated not to act upon paraformaldehyde even in the presence of sunlight at ordinary temperatures. However, on heating in a sealed tube at 120-125°C for 7 to 8 hours, reaction takes place with formation of methyl iodide, acetaldehyde, diiodomethyl ethei (ICH2OCH2I), carbon monoxide, and hydrogen iodide . In the presence of alkali, solutions of iodine in potassium iodide oxidize formaldehyde quantitatively to formic acid,...
