✦ Synopsis
The title compounds undergo silyl-Wittig rearrangement at low temperature and lead to allenolates at room temperature.
The mobility of both silicon and lithium in the system 2____ -3-4 forms the basis of syntheses of siloxyallenes 5 (and the corresponding cr,B-unsaturated ketones) from silyl keton-es ll.
