SELECTIVE ACYLATION FOR AROMATIC COMPOUND SUBSTITUTED WITH ALKYL GROUP OR ARYL GROUPAlkyl- or aryl-substituted aromatics are acylated by reaction with carboxylic acids or carboxylic anhydrides, esters or halides at temperatures in the range from -50 to +50 DEG C in condensed hydrogen fluoride.RAINAA...
An alkyl and/or aryl silyl ether capped polyether surfactant useful in cleaning compositions. The polyether is described in conjunction with automatic dishwashing detergent composition having improved chlorine bleach stability comprising:(a) an active chlorine containing compound selected from the group consi...
Metabolism of 2-naphthylamine produces the aryl-nitrenium ion, the ultimate carcinogen, from its conjugate in the acidic pH of urine. This explains why 2-naphthylamine is carcinogenic in the urinary tract and urinary bladder. Aralkylation Involves the Addition of an Aralkyl Group to DNA An ar...

5-[Substituted bicyclic aryl or heteroaryl]cyclohexane-1,3-dione herbicides The invention concerns novel compounds of the formula I ##STR1## wherein: A is selected from CH and N; B is selected from oxygen, sulfur, CH 2 and the group N-Z wherein Z is selected from the group consisting...
Novel -aryl-,-bis -(disubstituted amino) alkyl!acetamides are described herein. The compounds are useful as anti- arrhythmic agents. The compounds are prepared by reacting an appropriate disubstituted acetonitrile with an appropriate haloalkyl amine and subsequently hydrolyzing the resulting nitrile with...
This electronic effect is involved when the cyclopropyl group of efavirenz, a nonnucleoside reverse transcriptase inhibitor, interacts with the aromatic ring of tyr181 via a π-aryl interaction that is presumably favorable to binding [36]. The lipophilic effect of cyclopropyl explains why abacavir, ...
For example, tris(dimethylamino)sulfonium trifluoromethoxide (TASOCF3) was used as a trifluoromethoxylation reagent by Ritter’s group to achieve the direct trifluoromethoxylation of aryl stannanes and aryl boronic acids with equivalent silver25. Liu group reported a palladium-catalyzed intramolecular ...
