, p. 1133 - 1136 (2004)
A method for the selective α-monoallylation of phenyl ketones and benzocycloalkanones with allyl alcohol under microwave irradation is described. The corresponding α-allyl ketones are obtained in moderate to good yields with only minor quantities of diallylation by-products.

Nitrogen-containing heterocycles are prevalent in both naturally and synthetically bioactive molecules. We report herein an unprecedented protocol for radical aza-cyclization of α-imino-oxy acids with pendant alkenes via synergistic photoredox and cobaloxime catalysis. With or without alkenes as the intermolecular cross-coupling partners, the transformation provides a variety of corresponding alkene-containing dihydropyrrole products in satisfactory yields. In the presence of external alkenes, the tandem reaction generates E-selective coupling products with excellent chemo- and stereoselectivity.
'Propylene spaced' allyl tin reagents: A new class of fluorous tin reagents for allylations under radical and metal-catalyzed conditions
Curran, Dennis P.,Luo, Zhiyong,Degenkolb, Peter
, p. 2403 - 2408 (2007/10/03)
A new generation of propylene-spaced fluorous allyltin reagents [(Rf(CH2)3)3SnCH2CH=CH2] is described. These succeed in radical allylations where their lower homologs (ethylene-spaced) fail, and they provide improved performance in transition metal catalyzed allylations. The reagents and byproducts are readily separated by simple fluorous-organic liquid-liquid or solid-liquid extractions.
