Allylic phosphates allylate ketones and aldehydes in the presence of samarium(II) iodide. The coupling proceeds with the preservation of the olefin geometry, however, regio- and stereoselectivity are not high.

The regioselectivity of the coupling of phenoxyallyllithium with allylic electrophiles was investigated. The allylation pattern corresponded with the hardness of the leaving group and the highest α-selectivity was observed in the reaction with allylic phosphate.
