DIALLYL ETHER (557-40-4) Forms explosive mixture with air (flash point 20°F/—7°C oc). Forms explosive peroxides with air. Violent reaction with strong oxidizers, strong acids. Flow or agitation of substance may generate electrostatic charges due to low conductivity. 

This regioselectivity is reversed for olefins substituted with electron-releasing groups, and the 3-substituted pyridines are the predominant products. For example, reaction of 8 with allyl f-butyl ether gives 23 as the major product in 61% yield (Fig. 3.1). The 4-substituted pyridine 24 was isolated in 13% yield. The less-encumbered diallyl ether provided essentially the same ratio of 3- to 4-substituted pyridine products, indicating that this regiochemistry is in fact driven by electronic factors. 

Copper(I)-catalyzed intramolecular [2 + 2]-photocycloaddition of diallyl ethers and homoallyl vinyl ethers provides a new route to 3-oxabicyclo- and 2-oxabicyclo[3.2.0]heptanes, respectively.Different structural variants of diallyl ethers have been investigated. UV irradiation of diaUyl ethers 77a-f in the presence of CuOTf catalyst produces 3-oxabicyclo[3.2.0]heptanes 78a-f in moderate to excellent yields (Scheme 22). The diallyl ethers 77c and 77d having alkyl substitution at the aUyhc position produce exclusively the 2-exo-alkyl-3-oxabicyclo [3.2.0] heptanes 78c and 78d, respectively. The observed stereoselectivity arises through photocycloaddition of the Cu(l)-diene complex 80, which is stericaUy less crowded than the complex 81 with an axial alkyl group. The bicychc ethers 78 can be oxidized smoothly to the lactones 79 with RuO. Cu(l)-catalyzed photocycloaddition of homoallyl vinyl ethers 82 also proceeds smoothly, producing 2-oxabicyclo[3.2.0]heptanes 83 (Scheme 22).
