Sodium 2 methoxyethoxide, reaction

Sodium 2-methoxyethoxide, reaction -with vinylidene chloride to yield ketene di(2-methoxyethyl) acetal,... 

Dioxocomplexes of MIMVI02(0R)3 R = Me, Et, C2H,OMe composition [1638] are formed on the direct interaction of M02(0R)2 with M OR in alcohols (according to the data of conductometric titration) and with the exception of2-methoxyethoxides are very unstable. The stability against the ether-elimination reaction is apparently due to the stability of the molecular structures if the corresponding complexes as 2-methoxyethoxide complexes of sodium appear to be much more stable than those of lithium, due presumably to the small size of the atoms of the latter [902],... 

Vinylidene chloride, reaction with sodium 2-methoxyethoxide to yield ketenedi(2-methoxyethyl) acetal, 47, 78... 

Vinyl halides. Treatment of 5,5-dialkyl-N-nitrosooxazolidones (1) with lithium 2-methoxyethoxide in 2-methoxyethanol saturated with sodium iodide, lithium bromide, or lithium chloride leads to high yields of vinyl halides (3).] The reaction is considered to proceed through an unsaturated carbonium ion (2).
