Allyl propyl ether

A key report investigated a variety of substrates in their reaction with silicon in an effort to find evidence for silylene intermediates during the silicon direct process reaction. When silicon, copper and methanol were reacted as described above but in the presence of alkenes, alkyldimethoxysilanes and (MeO SiH were formed95-97. The use of allyl propyl ether instead of alkenes gave allyldimethoxysilane, with 38% selectivity. These results and the reaction of silicon with MeCl in the presence of butadiene to give silacyclopent-3-enes indicates intermediate formation of silylenes.

The copolymerization of ethene with TIBA-precomplexed allyl ethyl ether and allyl propyl ether has been catalyzed by 38/ MAO (Figure 19) and related zirconocenes. While the incorporation level of the allyl ethyl ether was highly dependent on the TIBA ether ratio, in case of the allyl propyl ether, the TIBA concentration had a negligible effect. However, for the latter case, the polymerization temperature had a high influence with an optimum at 45 °C. Furthermore, the copolymerization of TlBA-protected 2,7-octadienyl methyl ether with ethene has been reported recently. Different catalysts were employed, with the sterically protected zirconocene 38 (Figure 19) as the most active upon MAO activation. In this case, the catalyst even outperforms a late transition metal nickel a-diimine catalyst system (Section 3.24.4.2).

When carried out under standard conditions with Et3SiH/TFA, reduction of acrolein leads to a mixture of allyl alcohol, 1-propanol, and di-n-propyl ether in addition to allyl trifluoroacetate and -propyl trifluoroacetate.434 The 1,2-reduction of cinnamaldehyde with triethoxysilane in the presence of fluoride ion provides the corresponding allyl alcohol in good yields (Eq. 261).

Lallemand s group has also investigated an alternative route to the crucial aminocycloheptanone intermediate (46) via a Diels-Alder addition between an acylnitroso derivative (44) and a protected polyhydroxy-cycloheptadiene (45) [56]. Due to an inability to remove the allyl groups chosen for protection of the hydroxyl functionality, this approach has yielded a propyl ether derivative of calystegine B2 other protecting groups which can be removed with more facility should render the parent alkaloid accessible. 

Isomerisation of allyl ethers to enol ethers by Wilkinson s catalyst in refluxing aqueous ethanol is accompanied by competing reduction of the double bond to the propyl ether. " However, treatment of Wilkinson s catalyst with butyl-lithium results in a red rhodium catalyst that is able to isomerise a wide range of substituted and unsubstituted allylic ethers without competing reduc-tion. In the example shown in Scheme 4.215, the unpurified enol ether product was cleaved by treatment with a mixture of mercury(II) chloride and mercury(ll) oxide in acetone to liberate the anomeric centre in 91% yield for the two steps. ...
