A side reaction accompanied with catalytic hydration of acetylene. Part VIII. Appurtenant knowledge of the chemistry of mercarbide, mercuroform and polymercurated acetaldehydes (continued).

Abstract

a) The structure of Mercarbide (M.C.) and Mercuroform (M.F.) is shown by following general formulae ?? .(n=3 in M.C., n=2 in M.F.) The least strain in the ringsystem indicates that the trimeric molecule of M.C. must be in a perfectly stable form. On the contrary, the same amount of bond strain should be considered to be involved in dimeric stricture of M.F. molecule. The fact that most of the chemical and physical behavior of M.F. is extremely similar to that of M.C. shows that both possess nearly the same shaped formulae. b) Polymercurated acetaldehydes were classified into four groups according to the number of polymercurated methyl groups in each molecule and it was ascertained that the kinds of the sparingly soluble basic precipitates formed by alkali hydrolysis should be confined to either of M.C. or M.E.
