The reaction of equimolar amounts of 3-chloro-2-chloromethylpropene (2) and a carbonyl compound (3) with an excess of lithium powder and a catalytic amount (6%) of naphthalene in tetrahydrofuran at −78°C leads, after hydrolysis with water, to the corresponding diols 4 in a Barbier-type process.
水解后,等摩尔量的3-氯-2-氯甲基丙烯(2)和羰基化合物(3)与过量的锂粉和催化量的萘(6%)在四氢呋喃中的反应在-78℃下反应与水一起以Barbier型方法得到相应的二醇4。
