Abstract
A number of popular squaramide organocatalysts' acidities were determined by an overlapping indicator method in DMSO via UV spectrophotometric titrations. The pKa values are in the range of 8.37-16.46. The results may be helpful for the rational design and development of squaramide type new catalysts.
摘要
通过重叠指示剂法在 DMSO 中进行紫外分光光度滴定，测定了几种流行的 squaramide 有机催化剂的酸度。pKa 值在 8.37-16.46 范围内。结果可能有助于 squaramide 型新型催化剂的合理设计和开发。
