Description

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.
