摘　　要：以水为介质 ,方酸与脲及其衍生物顺利发生脱水缩合 ,合成了一类方酸单酰胺化合物——氨甲酰类氮氧方酸 3.方酸与芳基脲于水中的反应为A kind of monosubstituted squaric amide ——mono carbamoyl amide of squaric acid 3(MCASAQ) was prepared by the condensation of squaric acid (SQ) with urea or its derivatives in water. MCASAQs (3) may have some physiological activity for the ureido was brought into them. Meanwhile, the reaction of SQ with arylurea in water provided a new route to the preparation of Narylnitrogenoxosquaric acids.
