Abstract: Novel .alpha.-aminoacetamides are powerful stabilizers for organic materials subject to oxygen and heat degradation, and particularly for synthetic natural rubber and synthetic ester lubricants. A wide range of substituents on the amine and amide N atoms, and also on the saturated carbon atom, yields an array of stabilizers having a wide range of compatibility in compositions comprising various synthetic resinous compounds to be stabilized.Novel syntheses are provided utilizing at least one amine nucleophilic agent, a dichlorocarbene ion generating agent, and an alkoxide ion generating agent, which together in the presence of aqueous alkali and an onium salt, yield novel .alpha.-aminoacetamides in which a wide choice of substituents may be introduced. The nucleophilic agent may be a primary or secondary amine, or one of each. The dichlorocarbene ion generating agent is a haloform. The alkoxide ion generating agent may be a ketone, an aldehyde, or a cyanohydrin which reacts with the haloform. An .alpha.

Abstract: Disclosed are new azo dyes prepared by diazotizing selected substituted anilines and coupling with aniline couplers containing sulfate ester groups. These dyes impart fast yellow to reddish-orange shades on polyamide fibers and also color cellulose acetate and wool. The dyes have the following general formula: ##STR1## wherein R is selected from a variety of groups such as alkyl, alkoxy, aryl, cycloalkyl, aryloxy, NH.sub.2, and NH alkyl; X is hydrogen, halogen, alkyl, or the like; Y is hydrogen or halogen; R.sub.1 is selected from groups such as hydrogen, alkyl, alkoxy, halogen, acylamido, alkylthio, and aryloxy; R.sub.2 is selected from such groups as hydrogen, alkyl, aryl and cycloalkyl; Z is a linking group such as alkylene; M is H.sup.+, Na.sup.+, K.sup.+, or NH.sub.4.sup.+ ; and m is 0, 1, or 2.
Abstract: N-substituted-4-(polyfluoro-2-hydroxy-2-propyl)anilines and compounds related thereto, useful as antihypertensive agents, are prepared by reaction of an N-substituted aniline with a polyfluoroacetone.
Abstract: A process for the preparation of an anthranilamide of the formula ##STR1## in which R.sub.1 and R.sub.2 each independently is hydrogen orC.sub.1 to C.sub.4 alkyl, or R.sub.1 and R.sub.2, together with the nitrogen atom to which they are bonded, form a heterocyclic ring,comprising reacting isatoic anhydride of the formula ##STR2## with an approximately equimolar amount of an amine of the formula ##STR3## in water at a pH of about 7 to 10.5 and a temperature of about 20.degree. to 100.degree. C. Advantageously the reaction is effected in the presence of a buffer system comprising an amine of the formula ##STR4## plus at least one of a hydrohalide and carbonic acid salt of such amine, e.g. ammonia or a lower alkyl amine plus the corresponding hydrochloride and/or carbonate.
Abstract: Substantive sunscreen agents which are neutralized or quaternary ammonium salts of esters or amides of p-aminobenzoic acid, p-nitrobenzoic acid or salicylic acid with choline, lecithin, hydroxyalkyl-substituted imidazoles, 2,2-dialkylamino alkanols or alkylamines, pyridinesulfonamide, or colaminomethylformyl chloride; or omega halogenoalkylethers of salicylic acid quaternized with tertiary amines. This is a continuation of application Ser. No. 339,974 filed Mar. 12, 1973, which is a divisional application of Ser. No. 130,533, filed Apr. 1, 1971, both now abandoned.
Abstract: Aromatic amines are obtained in high yield and purity by treating the corresponding cyclohex-2-en-1-on-oxime hydrochlorides with the at least threefold molar amount of acetic anhydride.
Abstract: The present invention relates to new N-substituted anilines which correspond to the general formula: ##STR1## in which R.sub.1 represents an alkyl radical or substituted alkyl radical, R.sub.2 represents a hydrogen atom, an alkyl radical or substituted alkyl radical, R.sub.3 represents a cyano, carbamoyl, carboxy or carbalkoxy radical and R.sub.4 represents a hydrogen or halogen atom or an alkyl or alkoxy radical. These compounds are valuable intermediates for the preparation of coloring materials, especially as coupling compounds for the synthesis of azo dyes.
