General description
trans-1,2-Dichloroethylene is an organic solvent used in freon cleaning agents.
Application
trans-1,2-Dichloroethylene can be involved in the synthesis of:
- (E)-Chloroenynes by reacting with 1-alkyne and piperidine in the presence of PdCl2(PPh3)2 catalyst in ethyl ether as a solvent.
- (E)-3-trimethylsilyl-1-chloro-1-propene by reacting with trimethylsilylmethylmagnesium chloride (TMSCH2MgCl) in the presence of Co(II) or Co(III) acetylacetonate.
- trans-1,2-Bis(tri-n-butylstannyl)ethylene which is an important reagent for the synthesis of myriad of natural products.
- trans-1-Chloroalkenes by reacting with Grignard reagents in the presence of tetrakis(triphenylphosphine)nickel as catalyst.

Highly functionalised benzofurans have been prepared from ortho-hydroxyphenones and 1,1-dichloroethylene. The key intermediate, a chloromethylene furan, smoothly rearranged into the corresponding benzofuran carbaldehyde under acidic conditions. Some mechanistic investigations have been performed and several biologically active benzofurans have been synthesised.
