A general method for acylation of indoles at the 3-position with acyl chlorides in the presence of dialkylalu- minum chloride. Org. Lett. 2000, 2, 1485-1487.Okauchi, T.; Itonaga, M.; Minami, T.; Owa, T.; Kitoh K.; Yoshino, H. A general method for acylation of indoles at the...
The molecular structure of the end groups of the substituted chlorotriazine-capped polyphenylene ethers is believed to correspond to formula I. It is also appropriate, however, to define said capped polyphenylene ethers in terms of the method for their preparation. ...
5.The method of claim 1, wherein the nitrone comprises an aryl nitrone structure represented by the formula (XXXXVI):wherein Z is (R3)a-Q-R4— or R5—; Q is a monovalent, divalent or trivalent substituent or linking group; wherein each of R, R1, R2and R3is independently hydrogen, ...

This paper describes a general derivatization HPLC method for the determination of aromatic and aliphatic acyl chlorides in lipophilic drug substances. Since most drug substances have weak absorptions in the visible range (above 380nm), the nitro-substituted anilines and nitro-substituted phenylhydrazine...
Reactions at 35 °C of acyl chlorides with o-mercaptophenol in tetrafluoroboric acid–ether or boron trifluoride–ether complex gave excellent yields of the corresponding 2-substituted 1,3-benzoxathiolylium tetrafluoroborates. Reduction of the products with sodium borohydride (or sodium borodeuteride)...
