In the course of the study on the chemistry of sulfoximine, we found that CHC13 decomposes violently when it is treated with NaOH in dimethyl sulfoximine. However when the decomposition was carried out in the presence of cyclohexene, 7,7-dichlorobicycloC4.l.Olheptane was obtained only in 5% yield wi

## Abstract The discovery of dichotomous reactivity in the reaction of trialkyl‐ vs. triphenylphosphane HBr salts with acetals allows entry to functionalized α‐methoxy phosphonium salts and a novel process for tertiary phosphane methylation. The new protocol opens a general entry to the synthesis o
