Triarylmethane dyes can be grouped into families according to the nature of the substituents on the aryl groups. In some cases, the anions associated with the cationic dyes (say crystal violet) vary even though the name of the dye does not.

Often it is shown as chloride. An extensive review of all the molecular descriptors, their mathematical definitions and properties are reported in an excellent book, which contains also a detailed reference list. Purity of the studied compounds, understood as the presence of some by-products or degradation products was proven earlier by NMR analysis in a DMSO solution.

The basicity of aromatic amines depends on the electron donation or electron withdrawing groups attached to the benzene ring, the more the number of electron donating group attached to the ring the more basic the compound will be.

It sounds like you might have generated a species with this structural moiety: This can happen if your solution was concentrated enough or the boiling of your ether was vigorous, so the local overheating caused the formation of $\ce{MgO}$, the guy above, and $\ce{Br-}$, which gives a very distinct bright red-pink color, which is VERY bright and only requires a bit of the side product to form.

Mar 01,  · The rearrangement of 2-thienyl- and 2-furylalkylpyridinium salts to the corresponding anilines by the action of methylammonium sulfites has been studied. It has been shown that the rearrangement of these salts is accompanied in many cases by the formation of phenols and dealkylation products.

Some of the confusion regarding this bacterial group stems from the fact that much of the work to date has involved parallel studies of TMAO and dimethyl sulfoxide reduction, and it is not yet known whether the two compounds are reduced by the same enzyme.

The reactions are heated in a sand bath to a temperature between C and C. May 10,  · Thionyl chloride and acetone, what happens. I tried to make 2,2-dichloropropanol from acetone and thionyl chloride, assuming that the following would happen: CH3C(=O)CH3 + SOCl2 --> CH3CCl2CH3 + SO2 I dripped in a few drops of thionyl chloride in acetone and then swirled the test tube.

This results in fairly quick formation of a golden yellow. An iodine(iii)-mediated, group-selective oxidative rearrangement of β,β-diarylenamines to α-amino ketones has been accomplished with excellent yield.

some quinone methides (R = C 6 H 5and 4-CH 3OC 6 H 4) this acid catalysis could be saturated, and analysis of the data obtained in the region of saturation for the example with R = 4-CH 3OC 6 H 4 produced both the equilibrium constant for the substrate protonation step and the rate constant for the rate-determining step.

Terpyridine was discovered inthey say, and has been shown to lend itself to the construction of specific, stable metal complexes with unique properties that can easily be tuned by the choice of the metal ion and/or the structural modification.DFT calculations clearly revealed that the rearrangement is sigmatropic and involves C-C bond formation and I-O bond cleavage in a concerted manner.

Acetic acid, which was found to be the best solvent for this protocol, would make the iodine atom more cationic and thus accelerate the sigmatropic rearrangement.

Some cookies are essential to.Triethylamine is commonly employed in organic synthesis as a base, most often in the preparation of esters and amides from acyl chlorides. Triethylamine is used to give salts of various carboxylic acid-containing pesticides, e.g. Triclopyr and 2,4-dichlorophenoxyacetic acid.
