Applications of Phase Transfer Catalysis, II. Synthesis of 2-Dihalogenomethyl-1,3-dioxolanes and 2-Dihalogenomethyl-1,3-dioxanes2-Substituted 1,3-dioxolanes 1a-35a react with dichlorocarbene generated by phase transfer catalysis via selective C(2)-H-insertion giving the 2-dichloromethyl-1,3-dioxolanes 1b-24b. and 26b-35b. In the same way the 2-dichloromethyl-1,3-dioxanes le, 2e, 4e-6e,12e, 26e, and 30e and the 2-dibromomethyl-1,3-dioxolanes 1c, 2c, 4c-6c, 12c, 26c, 28c, and 30c are prepared.
Notes:
2-Substituierte 1,3-Dioxolane 1a-35a reagieren mit durch Phasentransfer-Katalyse erzeugtem Dichlorcarben unter selektiver C(2)-H-Insertion zu den 2-Dichlormethyl-1,3-dioxolanen 1b-24b und 26b-35b. Ebenso entstehen die 2-Dichlormethyl-1,3-dioxane 1e, 2e, 4e-6e, 12e, 26e und 30e und die 2-Dibrommethyl-1,3-dioxolane lc, 2c, 4c-6c, 12c, 26c, 28c und 30c.
