Bis-allylic ethers

Tetrabromobisphenol A bis(allyl ether) finds some utility in expanded polystyrene foam. 

Catalytic tandem isomerization/Claisen reaction of bis allyl ether was reported by Dixneuf et al. [23]. A cationic bis-oxazoline-ruthenium-arene complex S3 in the presence of both l,3-bis(2,6-diisopylphenyl)imidazolinium chloride and CS2CO3 catalyzes the selective transformation of bis-allyl ether 51 into ) c5-unsaturated aldehyde 52 via successive alkene isomerization and Claisen rearrangement (Eq. 12.21). 

Nickel catalysts also catalyze Grignard substitution to allylic compounds including allyl alcohol [230-233] ethers [230,231,234,235 Eq. (106) 231] amines, albeit in a low product yield [231] sulfides [231,236,237], including thioacetals [238] thiols [231] selenides [239] carboxylates [240] phosphates [94,121] and halides [Eq. (107) 230], most likely via intermediate / -allyl-Ni species. Monosubstitution of bis-allyl ether was possible [Eq. (108) 235]. Most of the literatures cited in the foregoing disclosed regiochemical outcome associated with these allylic substitutions. 

For instance, the one-pot tandem reaction [2,3]-Wittig-anionic oxy-Cope rearrangement affords the unsaturated aldehydes 571 starting from the bis-allylic ethers 570 at a high level of stereocontrol (equation 224). It was shown that the efficiency of chirality transfer in anionic oxy-Cope rearrangements is determined only by the orientational preference of the oxyanionic bond in the precursors having a single carbinol carbon chiral center .

Brontinated PS is combined with antimony trioxide as a flame retardant. In addition, brontinated poly(phenylene ether) has been used. Other flame retardants are tetrabromocyclooctane, tetrabromovinylcyclo-hexene, or bis-(allyl ether) tetrabromobisphenol A. For the latter flame retardants, dicumyl peroxide is added as a synergist and the additives are used together with blowing agents.
