Catalytic Stereospecific Allyl—Allyl Cross-Coupling of Internal Allyl Electrophiles with AllylB(pin).
ChemInform, 2014Co-Authors: Amanda Batten, James P. MorkenAbstract:Application of internal electrophiles in catalytic stereospecific Allyl–Allyl cross-coupling enable the rapid construction of multisubstituted 1,5-dienes, including those with all carbon quaternary centers. Compounds with minimal steric differentiation can be synthesized with high enantiomeric excess.

copper catalyzed magnesium barbier reaction for γ selective alkyl Allyl coupling
Tetrahedron Letters, 2007Co-Authors: Ender Erdik, Melike KocogluAbstract:Abstract CuCN catalyzed alkyl–Allyl coupling under magnesium-Barbier conditions occurs regioselectively and affords predominantly the γ-products in good to high yields. This one-pot CuCN catalyzed reaction utilising Mg, an alkyl halide and an Allylic substrate in THF at room temperature provides an easy alternative to the classical CuCN catalyzed γ-Allylation of alkyl Grignard reagents.

backbone modified small bite angle diphosphines synthesis and molecular structures of m co 4 x2pc r1r2 px2 m mo w x ph cy r1 h me et pr Allyl r2 me Allyl
Journal of Organometallic Chemistry, 2007Co-Authors: Graeme Hogarth, John KilmartinAbstract:A range of new small bite-angle diphosphine complexes, [M(CO)(4) {X2PC((RR2)-R-1)PX2}] (M = Mo, W; X = Ph, Cy; R-1 = H, Me, Et, Pr, Allyl, R 2 = Me, Allyl), have been prepared via elaboration of the methylene backbones in [M(CO)(4)(X2PCH2PX2)] as a result of successive deprotonation and alkyl halide addition. When X = Ph it proved possible to replace both methylene protons but for X = Cy only one substitution proved possible. This is likely due to the electron-releasing nature of the cyclohexyl groups but may also be due to steric constraints. Attempts to prepare the bis(Allyl) substituted complex [Mo(CO)(4){Ph2PC(Allyl)(2)PPh2}] were only moderately successful. The crystal structures of nine of these complexes are presented.
