Radical Addition Reactions of 2-(Phenylseleno)propanedioates to Alkenes and Alkynes

Sunlamp photolysis of methyl or ethyl 2-(phenylseleno)propanedioate with a variety of alkenes and alkynes in benzene yielded addition products in good to excellent yields.The proposed mechanism involves a radical chain process in which addition of a malonate ester radical is followed by phenylseleno transfer.Monosubstituted alkenes, 1,1- and 1,2-disubstituted alkenes, terminal alkynes, and internal alkynes were shown to undergo this reaction.Addition to diallyl ether led to substituted tetrahydrofurans, characteristic of process involving initial addition, followed by cyclization prior to phenylseleno transfer.Vinyl arenes, conjugated dienes, and unsaturated carbonyl compounds proved unreactive.

An unprecedented arylselenylation of aryl halides with trifluoromethyl aryl selenonium ylides in the presence of copper is described. The reaction proceeded at 100-140 °C under ligand- and additive-free conditions for 3-20 h to form a variety of unsymmetrical diaryl selenides in good to high yields. Arylselenylation is easy to operate, has good functional group tolerance, and demonstrates the different reaction profiles of trifluoromethyl aryl selenonium ylides from the homologous trifluoromethyl aryl sulfonium ylides.
TANDEM RADICAL ADDITION TO TRANS-2-PHENYLCYCLOHEXYL VINYL ETHER AND 8-PHENYL-3-MENTHYL VINYL ETHER
Kinart, W. J.
, p. 1813 - 1819 (2007/10/02)
The one step double addition of dicarbethoxymethyl radical followed by trapping the phenyloseleno or the 2-carbethoxyethyl radical to trans-2-phenylcyclohexyl vinyl ether or 8-phenyl-3-menthyl vinyl ether has been studied.
