The ionizing power of liquid SO 2 is sufficient to induce reactions between acetals or S N 1‐active alkyl chlorides with allylsilanes without additional Lewis acids [Eq. (a), X OCH 3 , R PhCH(OCH 3 ), n ‐C 6 H 13 CH(OCH 3 ), etc.; X Cl, R Ph 3 C, PhMe 2 C, etc.]. Reactions in liquid SO 2 are economical and ecologically advantageous. An additional benefit: they are extremely simple to perform!
