3.7- dimethyl-10-ethyl mercury bromide

Bromomercuri-2 -methylthiophene.—To prepare this substance mercury 5 5 -dimethyl-2 2 -dithienyl (1-97 grams) and 1 8 grams of mercuric bromide in 100 c.c. of acetone are rapidly brought to the boil, then cooled in ice. The bromide is precipitated by the addition of water. Yield 3-5 grams. It crystallises from ethyl acetate in shining, white needles, melting at 179° to 180° C., and ha dng the usual solubilities. 

The same names are used in organic as in inorganic chemistry e.gf.,phenylsodium, ethyl-lithium, dimethyl-mercury not sodium phenyl, lithium ethyl, or mercury dimethyl) methylmercuric bromide chloromercuri-benzoic acid (ClHg C6H4 C02H). lUPAC rules to cover wide areas of this extensive field are in an advanced stage of preparation at the time this book goes to press.
