The recent report of the alkylation and subsequent debromination of bis(tribromomethy1) sulfone,2i, with trivalent phosphorus reagents provides an elegant route to dialkyl thiirene dioxides and thus to dialkyl acetylenes.
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.
The tr&benyLsnytbiyl dical gcperated dmnally (AIBN-I or pbmdmnicalty in tbe pmsemce ofan olefin yields tbe anti-Vv H$ addua after-by aitltwmacek add (TFA).
