The synthesis and some reactions of meso-ionic 1,2-dithioM-ones (388) have been recently reported. The brown compound 388, R = R = Ph, has been prepared by several methods (i) the reaction betw i l,l,3,3-tetrabromo-l,3-diphenylacetone (PhCBrjCOCBrjPh) and potassium ethyl xanthate, (ii) the reaction between 1,3-diphenyl-propanetrione hydrate and tetraphosphorus decasulfide, (iii) 1,3-diphenylpropanetrione with hydrogen sulfide-hydrogen chloride in ethanol-chloroform yields the salt 389, R = R = Ph, X = Cl, which gives the meso-ionic I,2-dithiol-4-one with triethylamine, pyridine, or aqueous sodium bicarbonate. ... [Pg.80]

Pyridine compounds in which phosphorus is directly attached to a ring carbon are relatively rare. Phosphorus nucleophiles are not able to replace ring hydrogen atoms in pyridines and pyridine 1-oxides. Some time ago it was found that pyridine yields a zwitterion (170) when it is heated under reflux in the presence of tetraphosphorus decasulfide (Scheme 105) (68MI20500). Recently, a product that contains a C—P bond was isolated after extended heating under the same conditions followed by treatment with hydrochloric acid (81 JCR(S)285). However, it is uncertain whether free pyridine undergoes reaction in this case. Attack by phosphorus nucleophiles on salts is well established. Af-Methylacridinium methosulfate affords a stable isolable 9,10-dihydro adduct (171) that readily forms a... [Pg.244]

The catalysed reaction of hydrogen sulfide on ketones or their acetals, or the thionation of carbonyl derivatives by tetraphosphorus decasulfide, or some modified version of this phosphorous compound as Lawesson, Davy and Heimgartner reagents are classically used [119, 120] to prepare the thioketones (2). [Pg.22]

More stable than many other thiocarbonyl compounds, thioamides have been known and used for a long time. Reliable methods of synthesis [119] were introduced as early as 1815 by Gay-Lussac for the reaction of nitriles with hydrogen sulfide and 1878 by Hoffman for the thionation of amides by means of tetraphosphorus decasulfide. [Pg.28]

Technical tetraphosphorus decasulfide (Stauffer Chemical Co) is employed. The product is weighed under nitrogen protection. [Pg.21]
