Heating organomercurial 34 resulted in the a-ehmination of phenyl mercury bromide, generating dichlorocarbene, followed by addition of benzaldehyde to form the corresponding carbonyl ylide 35. This ylide can be intercepted with dimethyl-acetylene dicarboxylate (DMAD) to produce dihydrofuran (36), which formed furan 37 through a dehydrochlorination process in 46% yield.

Another measure of solvent softness proposed is based on Raman spectroscopic measurements. It is the wavenumber shift Av of the Raman band for the symmetrical stretching of Br-Hg-Br in the solvent relative to that of gaseous mercury bromide (Persson 1986). A solvent softness scale, called Ds = [A (Hg-Br)/cm-J] has accordingly been established. An extension of this scale to further solvents is difficult in those cases where the solubility of mercury bromide is insufficient for the ca. 0.2 mol dm-3 required for the Raman spectral measurements. 

Bis[2-(2 -pyridyl)phenyl] tellurium dibromide prepared from 2-(2 -pyridyl)phenyl tellurium tribromide and 2-(2 -pyridyl)phenyl mercury chloride was isolated as the 1 1 adduct (m.p. 235-238°) with mercury bromide chloride1.

Very often, the replacement of a diazonium group by hydrogen is carried out using stable crystalline diazonium salts, such as the 1,5-naphthalenedisulfonates, "" 2-naphthol-l-sulfonates, "" tetrafluorobor-ates, " " """ hexafluorophosphates " and mercury bromides. ... 

A very good example of this last case is given us by the mixtures of mercury bromide and mercury iodide studied by Reinders. ... 

The liquid mixtures formed by melted mercury bromide and mercury iodide give on cooling a single sort of mixed crystals these are the isomorphous orthorhombic crystals of yellow mercury iodide. 

The mixtures of mercury bromide and of mercury iodide, studied by Reinders, furnish us with another very simple example of these propositions. 

It is known that when the temperature is lowered to about 126 , yellow mercury iodide changes over to the red iodide similarly, by a lowering of temperature, the mixed crystals of merciuy iodide and of mercury bromide, which are isomorphous with the yellow iodide and which play here the rdle of the a crystals, are transformed into mixed isomorphous crystals of red iodide, playing the rdle of the P crystals. 

Reinders has drawn for these crystals the curves F and t which are indicated in Fig. 87. These two curves unite for in a point whose ordinate is equal to the temperature of transformation of yellow mercury iodide into the red iodide, that is, at 126 . These two curves do not extend to the line OT where X=0 indeed, beyond a certain content in mercury bromide, one observes only the mixed a crystals. 

White phosphorus is heated to about SOCT in the middle portion of a glass tube whose two ends are kept the one at 350 (vapor of boiling mercury) and the other at 324 (vapor of mercury bromide). After an hour and a half, the part of the tube at 350 showed an orange-red coating, imiform and translucent, while the other end, at 324 , showed not the least trace of this, but instead a few drops of liquid white phosphorus.
