Depending on the reaction conditions, the product can be isolated in either the lactoid form A [2321-07-5] (2) or the quinonoid form B [56503-30-1] (3). These 9-phenylxanthenes are closely related stmcturaHy to the triphenyl methane dyes (4) and, like them, are cationic resonance hybrids. [Pg.398]

Many isocyanates have good adhesive properties and one of them, triphenyl-methane-pp /7"-triyl tri-isocyanate, has been successfully used for bonding of rubber. Isocyanates are, however, rather brittle and somewhat limited in application. Somewhat tougher products are obtained from adhesives involving both polyols and isocyanates, i.e. polyurethane-type materials. The major application of these materials to date is in the boot and shoe industry. [Pg.805]

Bis(l-methylimidazol-2-yl)methane and -ketone with the dimer [Rh(CO)2Cl]2 in the presence of sodium tetraphenylborate give the dicarbonyl complexes 68 (X CHj, CO L = CO) where the carbonyl ligands may easily be substituted by the triphenyl phosphine ligands to yield 68 (X = CH, CO L = PPh ) (99JOM(588)69). The bis(l-methylbenzimidazol-2-yl)methane analogs of 68 (X=CH2 L=C0, PPhj) can be prepared similarly. [Pg.135]

Anodic oxidation has been employed for water-soluble triphenyl-methane dyes. It has been shown that the formation of dye is an irreversible two-electron oxidation process.21-23 This method has been used for the oxidation of diamino triphenylmethane leuco compounds containing two to four sulfonic acid groups to obtain food-grade colored materials.24... [Pg.130]

In a specific example in the same paper [17], one polymer contained triphenyl-methane fragments and the other o-nitrophenol moieties (A and B, respectively, in Scheme 5.1). The triphenylmethane residues were reacted with an alkyllithium and converted to surface-confined trityllithium species. This derivatized polymer was then mixed with an excess of the second polymer and the combination was used in the stoichiometric benzoylation of y-butryrolactonc (Scheme 5.2) or of phenylace-tonitrile (Scheme 5.3). The procedure was also demonstrated successfully using solid sodium hydride instead of the lithiated polymer. [Pg.138]

Gram Stain A staining procedure used in classifying bacteria. A bacterial smear on a slide is stained with a purple basic triphenyl methane dye, usually crystal violet, in the presence of iodine/potassium iodide. The cells are then rinsed with alcohol or other solvent, and then counter-stained, usually with safranin. The bacteria then appear purple or red according to their ability to keep the purple stain when rinsed with alcohol. This property is related to the composition of the bacterial cell wall. [Pg.314]

The carbohydrate structure can, in principle, be unambiguously determined by use of enzymic hydrolysis. However, the method is quite laborious, and usually requires large amounts of sample. It should also be noted that, unless the samples are purified after each step, the amount of the carbanion needed for the methylation tends to become increased, and must, therefore, be assessed by means of the triphenyl-methane test in order to avoid undermethylation (see Section I). Blanks containing the enzyme used must also be analyzed in order to... [Pg.412]

There are two groups of triarylcarbonium pigments inner salts of triphenyl-methane sulfonic acids, and complex salts with heteropolyacids containing phosphorus, tungsten, molybdenum, silicon, or iron. [Pg.11]

Route B has the added advantage over route A of making it possible to perform a stepwise reaction of trichlorophenylmethyl-tetrachloroaluminate 122 (i.e., the complex compound formed fromtri-(chlorophenyl)methylchloride and A1C13) with various amines. It is thus possible to systematically synthesize triphenyl-methane pigments with two or three differently substituted arylamino groups. [Pg.546]
