, p. 4003 - 4013 (2019/06/24)
Asymmetric copper-catalyzed allylic alkylation between allyl bromides and alkyl Grignard reagents using a P-chiral monophosphorus ligand is described. A range of terminal olefins bearing tertiary or quaternary carbon centers were formed in good branched/linear selectivities and excellent enantioselectivities at copper loadings as low as 0.5 mol %.

The copper complexes of chiral spiro phosphoramidite and phosphite ligands were found to be effective catalysts in the asymmetric allylic alkylations of cinnamyl halides with dialkylzincs. The allylic alkylation products were obtained in high regioselecti
Synthesis of (E)-1-Aryl-1-alkenes via a Novel BF3·OEt2-Catalyzed Aldol-Grob Reaction Sequence
Kabalka, George W.,Li, Nan-Sheng,Tejedor, David,Malladi, Rama R.,Trotman, Sarah
, p. 3157 - 3161 (2007/10/03)
The reactions of aromatic aldehydes with ketones in the presence of various acids were examined. The reactions generate (E)-1-aryl-1-alkenes in the presence of boron trifluoride diethyl etherate in nonnucleophilic solvents.
