Highly Regioselective Allylation of α-Enones and Epoxides with Lithium Tetraallyllanthanoid Ate Complex
Fukuzawa, Shin-ichi,Sakai, Shizuyoshi
, p. 3308 - 3314 (2007/10/02)
Tetraallyllanthanoid ate complex (1), which was readily prepared in situ from tetraallyltin, lanthanoid trichloride, and butyllithium in tetrahydrofuran (THF), reacts smoothly with α-enones (3-11) with a high degree of 1,2-regioselectivity (1,2:1,4 = >99:

, p. 939 - 940 (2007/10/02)
The ?-allyl lanthanoid ate complex (1), which was prepared in situ from tetra-allyltin, the lanthanoid trichloride, and n-butyl-lithium in tetrahydrofuran (THF), reacts smoothly with α,β-unsaturated carbonyl compounds (3) - (11) with a high degree of 1,2-
Organomanganese (II) reagents XX1: Manganese mediated Barbier and Reformatsky like reactions. An efficient route to homoallylic alcohols and β-acetoxyesters
Cahiez,Chavant
, p. 7373 - 7376 (2007/10/02)
Allylic halides and α-bromoesters react with manganese metal in ethyl acetate; THF can also be used as solvent if a catalytic amount of zinc chloride is added to the reaction mixture. When the reaction is performed in the presence of various aldehydes or

Luche, J. L.,Petrier, C.,Gemal, A. L.,Zikra, N.
, p. 3805 - 3806 (2007/10/02)
Organocopper reagents can be formed from alkyl and aryl halides under ultrasonic irradiation and reacted in situ with enones to give in high yields of β-alkylated ketones
