Ethyl trichloroacetate for generation

Grubbs first generation metathesis catalyst 145 was found to be an active catalyst for the Kharasch addition, provided its metathesis activity for the chosen olefin is low [206]. Snapper and coworkers found at the same time that the Grubbs I olefin metathesis catalyst is efficient for the Kharasch addition of less activated halides, such as CHC13, 1,1,1-trichloroethane, or ethyl trichloroacetate, to olefins like styrenes, acrylates, or acrolein [207, 208]. 

The high yield of hexachlorocyclopropane is noteworthy for with dichlorocarbene generated from either ethyl trichloroacetate or chloroform the yield is only 0.2-1 %. 

Schweizer and O Neill, unsuccessful in an attempt to follow the Reutov-Eovtsova procedure using commercial potassium l-butoxide, developed a convenient synthesis of phenyl(trichloromethyl)mercury in which phenylmercuric bromide is treated with trichloroacetate anion generated in large excess from ethyl trichloro-acetate and commercial sodium methoxide. A mixture of 200 ml. of benzene, 0.18 mole of ethyl trichloroacetate, and 0.37 mole of pulverized phenylmercuric bromide is stirred for 1.5 mln< In an ice hath and 0.154 mole of sodium methoxide is added all... 

The enantioselective addition of dichlorocarbene to unsymmetrical olefins in the presence of a chiral phase-transfer catalyst has been further examined and it has been found that the optical rotation of the product is strongly dependent on the structure of the catalyst employed. The first products of di-iodocarbene (generated from iodoform with t-butoxide) addition have been characterized and di-iodonorcarane is stable for long periods at 0 °C, contrary to earlier reports. The base-catalysed decomposition of ethyl trichloroacetate in methanol results in dimethoxycarbene formation and.
