Soc., 61, 89 (1984): the melting point (175°) described in this literature must be that of the mixture of 3e and 3e′, In our experiment by this procedure, a mixture of 3e and 3e′ (molar ratio = 1) obtained from a reaction of 2e with 1,2-dibromoethane was obtained in a yield of 58%. Moreover, in a trial experiment of the preparation of 3c from 2c and 1,2-dibromoethane, we experienced the troublesome isolation of 3c from the reaction mixture. Thus this procedure is not simple and economical no matter how inexpensive the reagents used are.
