Vinylene carbonate dissolves in a variety of solvents such as ethanol, tetrahydrofuran, ethylene carbonate, propylene carbonate, and other dipolar aprotic electrolyte solvents used for lithium ion rechargeable batteries such as dimethyl carbonate, diethyl carbonate and the like.

In chemistry, vinylene (also ethenylene or 1,2-ethenediyl) [1] is a divalent functional group (a part of a molecule) [2] with formula −CH=CH−; [3] namely, two carbons, each connected to the other by a double bond, to an hydrogen atom by a single bond, and to the rest of the molecule by another single bond.
Ethylene carbonate (sometimes abbreviated EC) is the organic compound with the formula (CH 2 O) 2 CO. It is classified as the cyclic carbonate ester of ethylene glycol and carbonic acid. At room temperature (25 °C) ethylene carbonate is a transparent crystalline solid, practically odorless and colorless, and somewhat soluble in water.
When using lithium hexafluorophosphate (LiPF 6) salts dissolved in a carbonate solvent, one of the most frequently used electrolyte compositions, SEI formation can also be caused by chemical reactions between the electrolyte and trace amounts of water, producing hydrofluoric acid (HF) that further reduces performance.

Ketenes can also be formed from α-diazoketones by the Wolff rearrangement, and from vinylene carbonate by phosphorus(V) sulfide and irradiation. [6] Another way to generate ketenes is through flash vacuum thermolysis (FVT) with 2-pyridylamines. Plüg and Wentrup developed a method in 1997 that improved on FVT reactions to produce ketenes with ...
