Lardy, Samuel W.,Schmidt, Valerie A.
, p. 6796 - 6799 (2019/11/03)
A case study on the polarity effects of radical mediated intermolecular alkene aminoallylation is presented herein. This radical group transfer method pairs vinyl ethers with electronically deficient allyl-oxyphthalimide derivatives to give difunctionalized products while illustrating the guiding effects of polarity on this radical reactivity.

The development of a new chemical process that effects the conversion RH + C=C-C-X → R-C-C=C + HX, in which X is the phthalimido-N-oxyl radical (PINO·), is reported. The reaction yields are high, mass balances are excellent, and C-H bond functionalization and C-C bond formation are achieved in a single transformation. The byproduct of the reaction, N-hydroxyphthalimide, precipitates from solution and can be easily removed by simple filtration (and recycled). The kinetic chain lengths are shorter and the reaction times are longer (relative to those of the analogous reactions of allyl bromides), most likely because PINO· is a less-reactive hydrogen-atom abstractor. There appears to be no significant difference in efficiency in the addition-elimination steps. Competition experiments reveal that Br· and PINO· are comparable in leaving group ability.
