邢其毅等[1]研究了烷基、芳基格氏试剂对乙烯四羧酸四乙酯的加成,发现这类反应为1,4-加成[2~6].

According to the Grignard's method modified by Normant,by treating vinyl bromide, 2, 2-dimethyl vinyl bromide, 1, 2, 2-trimethyl vinyl bromide, 2-phenyl vinyl bromide and oyolohezenyl bromide respectively with metallic magnesium in tetrahydrofuran the corresponding vinyl magnesium bromides were prepared. Reactions of ethyl ethylene-tetraoarbogylate with aforementioned vinyl magnesium bromides gave the corresponding a-vinyl aubstituted ethyl ethanetetraoarbogylates 1~5 respectively.
