In analogy with the conventions applied for carbenoids, we will use the term “silylenoid” for a compound in which a metal atom and a leaving group are bound to the same silicon atom. The term “silylenoid character or nature” on the other hand will be used in more mechanistic sense for a species that reacts electrophilically.

In the absence of TMEDA, the ratio of 8/6 was 13/87 (54% total yield). The effect of TMEDA, however, is not clear and is now under study.

In carbenoid chemistry, ionization of this type is sometimes called “metalassisted ionization” which involves a definite heteroatom–metal interaction, according to Walborsky et al. [1i].

The methyl group in this model compound may not necessarily be bulkier than the lithium atom in 2, since the lithium atom must be solvated.

Our proposal is based on the reasonable assumption that the silylenoid character of lithium(alkoxy)silylenoids can be applied to the reactivity of metal(halo)silylenoids.

The sila‐Wittig rearrangement of (alkoxysilyl)lithium compounds, that is the organic group migration from oxygen to silicon, analogous to the Wittig rearrangement, has also been observed and will be reported in due course.
