We have found that cross-coupling between aryl Grignard reagents and allylic methyl ethers proceeded well in the presence of a catalytic amounts of Fe(acac) 3 to afford the corresponding allylic substitution products in good yields. Under the same conditions, allylic trimethylsilyl ethers also reacted with Grignard reagents to give the corresponding cross-coupling products.
Wittig rearrangement of lithiated allyl aryl ethers: A mechanistic study
Strunk, Sven,Schlosser, Manfred
, p. 4393 - 4397 (2007/10/03)
At -75°C, α-lithiated allyl phenyl ether undergoes mainly the [1,2] Wittig rearrangement to afford, after acidic hydrolysis, 1-phenyl-2-propen-1-ol as the main product. A second metalation taking place at one of the ortho positions is the sole competing s
Iridium-catalyzed enantioselective synthesis of allylic alcohols: Silanolates as hydroxide equivalents

(Chemical Equation Presented) Masked hydroxide: A highly regio- and enantioselective Ir-catalyzed allylic etherification of acyclic, achiral allylic carbonates can be achieved by using potassium silanolates as nucleophiles. The use of these hydroxide equi

, p. 2785 - 2788 (2007/10/03)
Alkenylation of aldehydes mediated by a catalytic amount of Cr(II)/Ni(0), using aluminium as an electron source, was performed to afford the corresponding allyl alcohol derivatives in good to moderate yields.
TRIS(2-METHYLPHENYL)PHOSPHORANE, A MODIFIED SEYFERTH-WITTIG REAGENT FOR THE STEREOSELECTIVE SYNTHESES OF Z-ALLYLTRIMETHYLSILANES

, p. 5965 - 5968 (2007/10/02)
The Wittig reactions between title β-silylphosphorus ylide and aliphatic aldehydes give selectively Z-allyltrimethylsilanes with minimal formation of vinylation products.
