Radicals / Addition 1 Stereoselectivity f Alkynes Alkanes can be added to alkynes in a thermally initiated freeradical chain reaction ("ane reaction"). The addition of cyclohexane to 1-alkynes la-1 yields a mixture of (4and (E)-2cyclohexyl-1-alkenes 3a-1. An essential step in this reaction is the ad
In a recent publication (1) we have reported the light-induced addition of acetals to olefins which led to the corresponding monoalkyl acetal derivatives. We report now the peroxide-induced addition of 1.3,5-trioxan to olefins at elevated temperatures.
