Sjoeholm, Rainer,Rairama, Riitta,Ahonen, Matthias
, p. 1217 - 1218 (1994)
The Zn mediated reactions of cinnamyl chloride with aldehydes and ketones in THF-NH4Cl(aq) give-besides α- and γ-addition products-phenyl propenes and dicinnamyls, indicating the presence of radical intermediates in the reaction.

supporting information, p. 3881 - 3884 (2014/07/08)
An efficient synthetic method to prepare highly substituted indenes in moderate to excellent yields that relies on Br?nsted acid catalyzed Friedel-Crafts reaction of homoallylic alcohols under mild conditions is described.

The diastereoselective addition of γ-substituted allylic nucleophiles to ketones has been accomplished to give tertiary homoallylic alcohols. The reaction of tributylcinnamyltin 1a with simple ketones 2 in the presence of stannous chloride (SnCl2/su
Barbier/Grignard-type allylation or benzylation mediated by the mischmetall/SmI2(cat.) system

, p. 2989 - 2995 (2007/10/03)
Barbier- and Grignard-type allylation and benzylation have been achieved by the use of samarium diiodide in catalytic amounts together with mischmetall (an alloy of the light lanthanides) as a coreductant. Plausible catalytic schemes are proposed. In addition, organocerium and -lanthanum reagents have been obtained from samarium diiodide catalysed reactions between organic halides and cerium or lanthanum metal, giving a new route to organolanthanoid compounds. It also appears that trivalent benzyl and allyl organometallic compounds of cerium and lanthanum are much more stable than the corresponding samarium ones.

Samarium(II)-mediated reaction of allylic phosphate esters with carbonyl compounds: A new method for "Umpolung" of allylic phosphates
Araki, Shuki,Hatano, Masahiro,Ito, Hirokazu,Butsugan, Yasuo
, p. 329 - 336 (2007/10/02)
Allylic phosphates allylate ketones and aldehydes in the presence of samarium(II) iodide.The coupling proceeds with the preservation of the olefin geometry ever, regio- and stereoselectivity are not high.
