There is a starting material that I would like to have that is no longer commercially available (trichloromethanesulfinyl chloride). The only published route I have found involves the use of hydrogen sulfide gas, which is quite toxic. I have standard glassware available to me. How difficult would it be to use hydrogen sulfide in a reaction? The earliest I would perform this reaction is a couple of months from now, and I have a little NaSH in the lab at the moment, which I could potentially use to generate H2S if that would be safer.
