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...

aryltetrazoles containing a 5-alkyl substituent withphenyllithiumor phenylsodium gives 5-(α-metalloalkyl)tetrazole derivatives (165) which undergo normal substitution reactions (Scheme 24). The tetrazole 5-CH2moiety of 5-benzyltetrazoles may be oxidized to a carbonyl group under controlled conditions...
Dehydrogenative Coupling of Alkyl or Arylsilanes Catalyzed by Ti(O-i-Pr)_4 Oligo (monosubstituted silanediyl)s have attracted much interest as a component of advanced materials and also as a source of silylenes. Ti(O-i-Pr)4, which is cheap and easily available, selectively catalyzes ...
