Palladium on carbon catalyzed cross-coupling between alk-1-ynes and 2-chloro-4,6-dialkoxy-1,3,5-triazines
摘要:
2-(Alk-1'-ynyl)-4,6-dialkoxy-1,3,5-triazines have been synthesized in satisfactory yields by (Pd/C)/PPh3/CuI catalyzed cross-coupling between alk-1-ynes and 2-chloro-4,6-dialkoxy-1,3,5-triazines carried out in the presence of diisopropylethylamine or K2CO3/18-crown-6.

Selective Mono- or Dialkoxylation of 2,4,6-Trichloro-1,3,5-triazine in Solid-Liquid Phase Transfer Conditions
摘要:
In solid-liquid phase transfer conditions, both the primary and the secondary alcohols react cleanly with 2,4, 6-trichloro-1,3,5-triazine to give the corresponding mono or dialkoxy derivatives depending on the reagent molar ratio.

Aryloxytriazine-capped polyphenylene ethers are prepared by reaction of a polyphenylene ether with an aryloxychlorotriazine such as diphenyl chlorocyanurate. The products undergo reaction with amine-terminated polymers such as polyamides, to form compositions which have excellent properties and which find utility as molding compositions and as compatibilizers for blends of similar polymers.

Aryloxytriazine-capped polyphenylene ethers are prepared by reaction of a polyphenylene ether with an aryloxychlorotriazine such as diphenyl chlorocyanurate. The products undergo reaction with amine-terminated polymers such as polyamides, to form compositions which have excellenr properties and which find utility as molding compositions and as compatibilizers for blends of similar polymers.
A method for the preparation of polyphenylene ether resins having increased hydroxyl content and, particularly, increased non-Mannich hydroxyl content comprises reaction of biphenol with polyphenylene ether resin. Polyphenylene ether resins obtained by such method, as well as the reaction products between such polyphenylene ether resins and hydroxyl-reactive substituents, such as epoxy chlorotriazines, and compositions containing such reaction products and thermoplastic resins not normally compatible with polyphenylene ether resin, such as polyester resin are also disclosed.
