In order to investigate their potential applications as additives, we synthesized the allyl-terminated hyperbranched PAEKs (HBP-AL) via an etherification between HBP-OH and allyl bromide and incorporated HBP-AL into the bismaleimide (BMI) resins based on 4,4'-bismaleimideodiphenylmethane (BMDM, Chart 1) and 2,2'-diallylbisphenal A (DBA).
ATV-Dimethylacetamide (DMAc, [greater than or equal to] 99%) and allyl bromide ([greater than or equal to] 98%) were purchased from Sinopharm Chemical Reagent Co.
Value Recovery's technology can also be used to convert hazardous byproducts like methyl chloride, allyl bromide
, phenol, acrylate, and cyanide found in either air or dilute water streams into useful chemicals.
Various aldehydes were cleanly allylated with indium and allyl bromide
in liquid carbon dioxide.
Using alkynylmagnesium bromides and allyl bromide
, we investigated modifications of the known Cu(I) catalyzed coupling reaction (Davini et al.
(CAS 106-95-6) Market Research Report 2009
Table 2 shows that the reactivity of brominated compounds is larger than that of chlorinated compounds and allyl bromide reacts quantitatively with sodium-metallated PMIA at 20 [degrees] C.
Sodium-metallated PMIA reacted quantitatively with benzyl bromide and allyl bromide.
