For convenience, the term “cycloaliphatic functionality” is defined herein to encompass a wide range of functional groups such as alkyl groups, alkenyl groups, alkynyl groups, haloalkyl groups, conjugated dienyl groups, alcohol groups, ether groups, carboxylic acid groups, acyl groups (for example...
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. ...

Acyl chlorideSm(0)/Bu3PReductionA facile and efficient reduction of aromatic and aliphatic acyl chlorides to their corresponding aldehydes in the presence of Sm(0)/Bu 3 P has been developed with a broad scope. This method prevents over-reduction of products, that is, the over-reduction of ...
Acyl chlorides couple with Grignard reagents at room temperature in the presence of catalytic amounts of tris(acetylacetonate)iron(III), Fe(acac) 3 . The reaction is general with respect to both reactants and provides a very mild and convenient method for the synthesis of aliphatic and ...
5. A curable composition, comprising: a functionalized poly(arylene ether); wherein the functionalized poly(arylene ether) is a ring-functionalized poly(arylene ether) comprising repeating structural units having the formula wherein each L1-L4 is independently hydrogen, an alkenyl group, or an alkyn...
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, ...
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)...
