title: All-carbon-substituted vinylsilane stable to TBAF: synthesis of allyldimethylvinylsilane and its Pd-catalyzed cross-coupling under mild conditions.
abstract: [reaction: see text] Allyldimethylvinylsilanes 3 are easily synthesized by the reaction of silylallylmetals, generated from 1 by n-BuLi/t-BuOK, with carbonyl compounds in the absence or presence of metal halides. They can tolerate 2 equiv of TBAF in THF at room temperature for at least 6 h but can be easily activated in the presence of a palladium catalyst and TBAF to perform the cross-coupling reaction with aryl iodides at room temperature.
