ABSTRACT:
The invention relates to a process for the industrial scale synthesis of vinyl and isopropenyl chloroformates and thiochloroformates.
According to the invention, phosgene or thiophosgene is reacted, at between 20.degree. and 70.degree. C., with a mercury salt XHg(CH.sub.2 CRO), in which X=Cl or --CH.sub.2 CRO, where R=H or CH.sub.3, in the presence of a solvent or a mixture of solvents having a dielectric constant greater than 10. The process can also be carried out using a mixture of the above solvents with a solvent which is not effective by itself (solvent of low polarity) but which is inexpensive. The yields achieved can exceed 90%.
