摘要: 自1876年Reimer-Tiemann反应(以下简称R-T反应)提出后,许多化学工作者曾对该反应进行了深入研究[1~5]。1988年丁新腾等又报道了叔胺存在下的反常R-T反应[6]。但以聚乙二醇(PEG)为相转移催化剂,催化R-T反应未见报道。

Abstract: Reimer-Tiemann reaction under phase transfer catalysis of poly (ethylene glycols) (PEG) has been studied. It has been shown that PEGhave an obvious catalytic effect on the reaciton and the ratio of the para- and ortho-products is abnormal. Such an abnormal Reimer-Tiemann reaction has not been reported in literature. The conditions of the abnormal Reimer-Tiemann reaction were studied in detail and a mechanism was proposed.
