以二乙氨基三甲基硅烷(DEATMS)为催化剂,在离子液体中,以三氟乙醛缩乙半缩醛或二氟乙醛缩乙半缩醛为原料,一步合成了2-取代的3-三(或二)氟甲基-2-丙烯醛,并证明该路线使我们能够成功地构建2-取代的3-三(或二)氟甲基-2-丙烯醛类化合物具有高水平的几何异构体选择性。
Investigation of one step synthesis of 2-substituted 3-tri-(or di-)fluoromethyl-2-propenals has been carried out using versatile aldehydes, tri- or di-fluoroacetaldehyde ethyl hemiacetal in the presence of diethylaminotrimethylsilane (DEATMS) in an ionic liquid, and it was demonstrated that this route enabled us to successfully construct 2-substituted 3-tri-(or di-)fluoromethyl-2-propenals with the high level selectivity of geometric isomers.
